Mastering LinkedIn Advert Size: Your Definitive Guide for 2025

So, you're looking to get your message out there on LinkedIn, right? Good shout. But here's the thing: messing up your advert's size is like turning up to a fancy dinner in your pyjamas. It just doesn't work. This guide is all about making sure your LinkedIn adverts look spot-on in 2025. We'll cover everything from photos to videos, making sure your stuff grabs attention for all the right reasons. Getting your linkedin advert size right is pretty important, actually.

Key Takeaways

• Getting your linkedin advert size correct helps your ads look good and perform better.
• Different ad types on LinkedIn need different sizes for images and videos.
• Mobile users are a big deal, so make sure your ads look good on smaller screens.
• There are tools out there to help you resize things if you're not a design whizz.
• Always check how your ad looks before it goes live to avoid silly mistakes.

Why Your LinkedIn Advert Size Matters More Than Your Aunt Mildred's Fruitcake Recipe

Let's be honest, Aunt Mildred's fruitcake is a yearly tradition, but does it really make an impact? Probably not. Your LinkedIn advert, on the other hand, can make a huge difference, but only if it's sized correctly. Think of it this way: a perfectly sized advert is like a well-tailored suit, while a badly sized one is like wearing your pyjamas to a job interview. Not a good look, is it?

The Perils of a Squashed Advert: Nobody Likes a Misfit

Imagine clicking on an advert only to find it's stretched, pixelated, or cut off. It screams unprofessional, right? It's like turning up to a meeting with your shirt inside out. A properly sized advert shows you care about the details, and that reflects well on your brand.

• It looks unprofessional.
• It can damage your brand's reputation.
• People are less likely to engage with it.

Making Your Advert Pop: The Visual Feast

Think of your advert as a delicious visual feast. A well-sized image or video is like the perfectly plated dish – appealing and inviting. A poorly sized one? More like a dog's dinner. You want people to stop scrolling and take notice, and that starts with getting the dimensions right. It's about creating a high-converting campaign that grabs attention.

First Impressions: The Digital Handshake

In the digital world, your advert is often the first interaction potential customers have with your brand. It's your digital handshake. A crisp, clear, and correctly sized advert says, "We're professional, we care about quality, and we're worth your time." A blurry, distorted mess says, well, the opposite. Don't let a bad advert size ruin that crucial first impression. It's all about ensuring your effective LinkedIn Ads are accurately captured.

Getting your advert size right is a simple thing that can make a massive difference. It shows you're paying attention, and that you value your audience's experience. Don't let a technicality let you down.

The Nitty-Gritty of Image Advert Sizes: Don't Be a Square (Unless It's a Square Advert)

Right, let's get down to brass tacks. Image adverts on LinkedIn. You might think, 'a picture's a picture, right?' Wrong! Size matters, especially when you're trying to grab the attention of busy professionals scrolling through their feeds. We're talking about making a visual impact, not just taking up space. So, grab a cuppa, and let's dive into the specifics.

Single Image Adverts: The Classic Choice

Ah, the single image advert – the reliable old workhorse of LinkedIn advertising. It's straightforward, but that doesn't mean you can just chuck any old picture up there. You need to make sure it's the right size and resolution to avoid looking like a blurry mess. Think of it as your digital handshake; you want it to be firm and confident, not limp and awkward. Aim for 1200 x 627 pixels for these bad boys. This ensures your advert looks crisp and professional, whether it's viewed on a desktop or a mobile device. Remember, first impressions count!

Carousel Adverts: More Than Just a Pretty Face

Carousel adverts are where you can really show off. Multiple images, multiple messages, multiple chances to hook your audience. But with great power comes great responsibility... to get the sizes right! Each card in your carousel should be 1080 x 1080 pixels. This square format is perfect for mobile viewing and keeps everything looking neat and tidy. Think of it as a digital brochure, each page needs to be perfectly presented. Carousel adverts are great for:

• Showcasing multiple products
• Telling a story
• Highlighting different features

Spotlight Adverts: Shine Bright Like a Diamond

Spotlight adverts are all about making a statement. These appear on the right-hand side of the LinkedIn feed and are designed to grab attention. The recommended size for the company logo is 100 x 100 pixels, and the custom background image should be 300 x 250 pixels. These adverts are all about visual appeal, so make sure your images are high-quality and relevant to your message. Think of it as your brand's digital billboard – make it eye-catching!

Getting the image sizes right is only half the battle. You also need to make sure your images are engaging and relevant to your target audience. A/B testing different visuals can help you identify what resonates best with your audience and improve your advert's performance.

Video Advert Dimensions: Because Nobody Wants a Pixelated Panto

Right, let's talk video. Nobody wants to watch a blurry mess, especially when you're trying to look professional. Think of it this way: a pixelated video is like turning up to a job interview with your trousers on backwards. Not a good look, is it? So, let's get those dimensions sorted.

In-Feed Video: Your Moment in the Limelight

In-feed videos are your chance to shine right in the middle of the LinkedIn feed. It's like having your own mini TV slot, so you want to make it count. Make sure your video grabs attention quickly, because people scroll faster than you can say 'engagement'.

Here's the lowdown on what you need to keep in mind:

• Aspect Ratio: You've got options! 16:9 (landscape), 1:1 (square), or 9:16 (vertical). These days, square and vertical are getting more love because of mobile viewing.
• File Format: MP4 is your only friend here. No other formats allowed, sorry!
• File Size: Keep it between 75KB and 500MB. Nobody wants to wait an age for your advert to load.
• Duration: You can go from 3 seconds to a whopping 30 minutes, but honestly, aim for 15-30 seconds. People have the attention span of a goldfish.
• Resolution: Minimum 720p, but 1080p is recommended. Think HD or go home.
• Codecs: H.264 or VP8 are the ones to use.
• Frame Rate: Up to 30fps. Anything higher will be automatically adjusted down, so don't bother.

Remember, videos on LinkedIn start muted. So, captions are not just a nice-to-have; they're essential. Upload an SRT file to make sure everyone can understand your message, even with the sound off. It's all about accessibility, innit?

Square and Vertical: The Modern Masterpieces

Listen up, because this is important: mobile is king. Square (1:1) and vertical (9:16) videos are the darlings of the LinkedIn world right now. Why? Because they fill the screen on smartphones, grabbing more attention. It's all about that prime LinkedIn banner real estate, you see.

The Goldilocks Zone: Not Too Big, Not Too Small

Finding the right balance is key. You don't want a video that's so small it looks like it was filmed on a potato, but you also don't want a file so massive it takes forever to load. Aim for that sweet spot where quality meets efficiency. Think Goldilocks and her porridge – just right!

Text Adverts: Small But Mighty (Like a Chihuahua with a Megaphone)

Text adverts on LinkedIn? They might seem a bit old-school in a world of flashy videos and interactive carousels, but don't underestimate them. Think of them as the chihuahuas of the advertising world – small, but with a surprisingly loud bark. When done right, these little guys can really pack a punch.

The Art of the Concise Message

Getting your point across in a tiny space is an art form. You've got to be laser-focused. Every word needs to earn its place. Think haiku, but for business. What's the core message? What action do you want people to take? Cut the fluff and get straight to the point. It's like trying to explain quantum physics to a toddler – simplicity is key.

Where Do These Little Wonders Live?

These text adverts usually pop up at the top or side of the LinkedIn feed. They're designed to be unobtrusive, but eye-catching enough to grab attention. They blend in, but they also stand out. It's a delicate balance, like trying to parallel park a monster truck in a bicycle lane. You'll often see them on the homepage, profile pages, and in search results. Knowing where they appear helps you tailor your message to the context.

Beyond the Words: The Tiny Image That Packs a Punch

Okay, so it's a text advert, but there's usually a tiny image involved too. This is your chance to add a bit of visual oomph. A logo, a relevant icon, something that catches the eye. Think of it as the cherry on top of your advertising sundae. Make sure it's clear, relevant, and doesn't look like it was designed by a committee of hamsters. A good image can significantly improve your LinkedIn banner sizes click-through rate.

Text adverts are all about making a big impact with minimal resources. They're perfect for quick announcements, targeted promotions, or simply getting your brand in front of the right people. Don't dismiss them – they might just be the secret weapon in your LinkedIn advertising arsenal.

Message Adverts: Sliding into DMs with Style (and the Right Size)

So, you fancy popping into someone's DMs, eh? Message adverts on LinkedIn are your digital equivalent of sliding a note across the classroom – but hopefully, a bit less awkward. Get the size wrong, and you'll end up looking like you've got no clue. Get it right, and you're one step closer to a connection (and maybe even a conversion!).

The Banner That Speaks Volumes

Think of your message advert banner as the headline act. It's the first thing people see, so it needs to grab their attention. We're talking about a relatively small space, so make every pixel count. A clear, concise image that reflects your brand is key. Don't go chucking a load of text on there; let the visuals do the talking. The recommended size is usually around 300x250 pixels, but always double-check the latest LinkedIn ad specs because they love to keep us on our toes.

Crafting Your Conversational Canvas

Your message advert isn't just about the banner; it's about the whole experience. You've got a limited amount of space to make an impact, so keep your message short, sweet, and to the point. Think about what you want to achieve with this advert. Are you trying to generate leads, promote an event, or simply raise awareness? Tailor your message accordingly.

• Use a clear call to action.
• Personalise where possible.
• Keep it conversational – nobody likes a robot.

Avoiding the Awkward Crop

There's nothing worse than an advert that looks like it's been through a digital meat grinder. Images stretched, text cut off – it's a visual disaster. Always preview your advert on different devices to make sure everything looks shipshape. Mobile is where most people will see your advert, so make sure it looks good on a smaller screen. If you're using a template, double-check the dimensions and make sure your content fits properly. A little bit of effort here can save you from a whole lot of embarrassment later.

Remember, your message advert is an invitation to start a conversation. Make it engaging, relevant, and visually appealing, and you'll be well on your way to DM success. Don't be that person with the pixelated panto – nobody wants that.

Document Adverts: When Your PDF Needs a Proper Pedestal

Let's be honest, a PDF on its own isn't exactly going to set the world alight. It needs a stage, a platform, a pedestal if you will. That's where Document Adverts come in. They're your chance to showcase those whitepapers, e-books, and reports in a way that actually grabs attention. Think of it as giving your PDF a makeover and a starring role.

Showcasing Your Whitepapers and E-books

Imagine your meticulously crafted whitepaper languishing in the digital depths, unread and unloved. Document Adverts rescue it! They allow you to present your content directly in the LinkedIn feed, making it super easy for people to access. It's like having a mini-bookshop right on LinkedIn. No more hiding your brilliance; let it shine!

The Preview That Entices

Think of the preview as the movie trailer for your document. You need to hook people in! A well-designed cover page is absolutely key. Make sure it's visually appealing and clearly communicates the value of what's inside. Use a compelling title and a brief summary to pique interest. If your cover image is boring, people will just scroll on by.

Making Your Content Look Cracking

It's not just about the cover, though. The overall presentation matters. Here are a few things to keep in mind:

• Use clear, readable fonts.
• Break up large blocks of text with headings and subheadings.
• Include visuals (charts, graphs, images) to make the content more engaging.

Remember, people are busy. They're not going to wade through a dense, poorly formatted document. Make it easy on the eyes, and they're much more likely to stick around and actually read what you've written. Think of it as digital hospitality.

Event Adverts: Getting the Party Started (Visually Speaking)

So, you're throwing a virtual shindig, a webinar wonder, or maybe even a real-life knees-up? Excellent! But nobody will come if they don't know about it, right? That's where LinkedIn event adverts strut their stuff. Think of them as your digital town crier, but way more stylish.

The Image That Invites

First impressions matter, especially when you're trying to get people to RSVP. Your event advert image is the bouncer at the door – it needs to be inviting, intriguing, and, most importantly, sized correctly. A blurry, stretched image screams 'unprofessional', and nobody wants to attend an unprofessional party. Aim for crisp, clear visuals that showcase what your event is all about. Think about using images of previous events, happy attendees, or even just a really snazzy graphic. A well-chosen image can be the difference between a packed house and an empty room.

Details, Details, Details: Fitting It All In

It's not just about the pretty picture, though. You've got to cram all the essential info into that little advert space. Date, time, location (virtual or otherwise), and a brief description of what attendees can expect. It's like writing a tweet, but with slightly more room to breathe. Make every character count! Use concise language and highlight the key benefits of attending. What will people gain? New skills? Networking opportunities? Free biscuits? (Free biscuits are always a winner.)

From Screen to Sign-Up: The Visual Journey

Your advert is just the first step. Once someone clicks, they need to land on a landing page that seals the deal. Make sure your LinkedIn header dimensions are consistent with your advert's branding and messaging. The sign-up process should be smooth and painless. Nobody wants to jump through hoops to attend your event. A clear call to action – 'Register Now!', 'Book Your Spot!', or even 'Tell Me More!' – is essential. And for goodness sake, make sure the link works! There's nothing more frustrating than clicking on an advert and ending up on a 404 error page. That's a surefire way to kill the party before it even starts.

Think of your event advert as a tiny, perfectly formed invitation. It needs to grab attention, convey essential information, and lead people seamlessly to the sign-up page. Get it right, and you'll be welcoming a crowd. Get it wrong, and you'll be left with a room full of empty chairs (or a virtual equivalent).

Follower Adverts: Growing Your Tribe with the Perfect Pic

So, you want more followers on LinkedIn? Excellent choice! Follower adverts are your secret weapon. Think of them as digital breadcrumbs, leading potential followers straight to your company page. But, like any good recipe, you need the right ingredients – and in this case, that means nailing the visual aspect. Let's get started, shall we?

The Profile Picture That Attracts

Your profile picture is basically the face of your brand on LinkedIn. It's the first thing people see, so make it count! Ideally, you want something clear, professional, and instantly recognisable. Think high-quality logo, not a blurry photo from your summer holiday in Benidorm.

• Size Matters: Aim for at least 400 x 400 pixels to avoid any pixelation nightmares. Nobody wants to see a fuzzy logo.
• Brand Consistency: Use the same logo across all your social media platforms. It helps with brand recognition, you see.
• Test it Out: See how it looks on different devices. Mobile is key, as most people browse LinkedIn on their phones.

Beyond the Logo: What Else Can You Show?

While your logo is important, don't be afraid to get a bit creative. You could use a lifestyle image that represents your company culture, or even a picture of your team. Just make sure it's relevant and professional. A picture of the office dog might be cute, but is it really going to attract serious followers? Probably not.

• Showcase Your Values: Use imagery that reflects what your company stands for. Are you all about innovation? Sustainability? Let your visuals do the talking.
• Highlight Your Products/Services: If you've got something visually appealing to show off, now's your chance. Just don't make it too sales-y.
• Consider a Tagline: A short, punchy tagline can add extra impact to your advert. But keep it brief – nobody wants to read a novel.

Making Your Brand Irresistible

Ultimately, you want people to see your follower advert and think, "Yes, I need to follow this company!" So, how do you achieve that? By creating an advert that's visually appealing, informative, and relevant to your target audience. Think about what makes your brand unique, and then showcase it in the best possible light. And remember, effective LinkedIn Ads can really boost your engagement.

Don't be afraid to experiment with different images and messaging. A/B testing is your friend. See what resonates with your audience, and then double down on what works. And most importantly, have fun with it! After all, marketing should be enjoyable, right?

Job Adverts: Attracting Talent with a Tidy Template

Let's be honest, job adverts can be a bit…dull. But they don't have to be! Think of your job advert as a dating profile for your company. You want to attract the right talent, and that starts with a visually appealing and informative advert. No one wants to swipe left on a blurry photo and a vague description, right?

The Image That Says 'Hire Me!'

First impressions matter, especially in the digital world. Your job advert image is your chance to grab attention. Ditch the stock photos of people shaking hands (unless that's really your vibe) and go for something that reflects your company culture. A picture of your team having a laugh, a shot of your cool office space, or even a creative graphic can work wonders. Just make sure it's high-quality and relevant. Think of it as the visual handshake that says, "Hey, we're awesome, and you could be too!" You can use LinkedIn Recruiter to find the best candidates.

Keeping It Professional, Yet Punchy

While personality is key, remember this is still a professional platform. Avoid anything too wacky or unprofessional. Here's a quick checklist:

• Clear Branding: Use your company logo and colours consistently.
• Relevant Imagery: Make sure the image relates to the job or your company culture.
• High Resolution: No one wants to squint at a pixelated mess.

Think of your job advert as a mini-billboard. You've got a limited space to make a big impact. Keep it clean, clear, and visually appealing.

The Visual Hook for Your Next Superstar

Ultimately, your job advert image is a hook. It's what gets potential candidates to click and learn more. So, make it count! A well-chosen image can be the difference between attracting your next superstar and being lost in the sea of mediocre job postings. Think about what makes your company unique and showcase that visually. It's all about creating a high-converting campaign that speaks to the right people.

Common Blunders and How to Dodge Them: Don't Be a Digital Disaster

The Stretched Image: A Visual Abomination

Oh, the stretched image. It's like seeing someone wearing clothes that are three sizes too small – just plain uncomfortable. The key is to always check your aspect ratio. Nobody wants to see a perfectly good logo turned into a distorted mess. It screams 'amateur hour'.

The Squashed Video: Nobody Wants a Flat Screen

Imagine watching your favourite film, but everyone looks like they've been flattened by a steamroller. That's what a squashed video does to your message. It's not just about the dimensions; it's about maintaining the integrity of your content. Think of it as giving your video a proper stage to perform on. To avoid this, consider A/B testing different video lengths to see what works best for your audience.

Ignoring Mobile: The Cardinal Sin of Advert Sizing

In 2025, if your advert isn't optimised for mobile, you might as well be shouting into the void. Most people are scrolling through LinkedIn on their phones, so a desktop-sized advert is going to look tiny and unreadable. It's like trying to read a billboard through a pair of binoculars – pointless. Make sure your text is legible, your images are clear, and your call to action is front and centre.

Mobile optimisation isn't just a nice-to-have; it's a necessity. If your advert looks rubbish on a phone, you're losing potential customers faster than you can say 'responsive design'.

Here's a quick checklist to avoid mobile mishaps:

• Always preview your advert on a mobile device.
• Use clear, concise text.
• Ensure your images are high-resolution and scale well.
• Test your effective LinkedIn Ads.
