Ever spent hours designing a beautiful ad—only to find it doesn’t show up right?
Or worse... it gets rejected, slows down your campaign, or just doesn’t perform?
That’s the reality many marketers face when they don’t follow ad size specs. In display advertising, size isn’t just about pixels. It's about performance, placement, and visibility.
If you're using AdRoll to run your campaigns, this guide will help you get your ads and CTAs right from the start, so they look sharp, load fast, and convert.
Let’s get your ads approved, your CTAs clicked, and your results moving!
To maximize visibility and campaign success, AdRoll recommends uploading at least these 6 core ad sizes (for both image and HTML5 formats):
You can also include these optional formats to expand your reach:
· 336 x 280 – Large Rectangle (great for content-heavy sites)
· 250 x 250 – Square (widely accepted and flexible)
· 200 x 200 – Small Square (tight spaces)
· 180 x 150 – Small Rectangle
· 120 x 600, 120 x 240 – Tall Skyscrapers
· 468 x 60 – Classic Banner (less common today)
Creating a beautiful ad isn’t enough. It must load fast, look great, and drive results.
Here’s how:
· Keep it light: File size must be under 150KB.
· Use bold, readable text: Especially for small sizes (like 320x50)
· Include a strong CTA: "Get Started," "Shop Now," "Subscribe."
· Add your logo: Branding builds trust and improves recall.
· Test your animation: Keep it subtle, clean, and under 30 seconds.
Pro Tip: Adding all 6 recommended ad sizes gives your ad a better chance to appear in top spots.
Creating stunning visuals is only half the battle — getting them approved and performing is the rest. To stop your ads from being rejected or showing up wrong, follow AdRoll’s technical rules when designing them.
Getting your ads live on AdRoll isn’t just about creative genius — it’s about checking the tech boxes too. From correct sizes and formats to animation timing and ClickTags, every detail matters.
These rules apply to both image and HTML5 ads. They help your ads work well on all devices and platforms.
· ClickTag: Required to track clicks.
· File Format: ZIP bundle (HTML, CSS, JS, media)
· Max File Size: 150KB
· Animation:
o Max duration: 30 seconds
o Looping allowed but must stop after 30 seconds
· Accepted formats: JPG, PNG, GIF
· Max File Size: 150KB
· Max speed: Slower than 5 FPS
· Max duration: 30 seconds
Make your ad recognizable instantly:
· Always include branding (logo, company name, or a recognizable brand element)
· Add a 1px border if your background is white or transparent
· No blurry logos — image quality matters
Over 60% of display ad impressions come from mobile. Don’t lose out because your text is too small or cut off.
Since many people see your ads on their phones, your designs must look good and work well on small screens.
Text and visuals must be legible on small screens — test readability on mobile view before uploading.
· Test legibility: View your ad on a mobile screen before uploading.
· Text character limits:
o Desktop: max 40 characters
o Mobile: max 20 characters
This ensures that your message is clear, not cut off, and accessible across devices.
Want more engagement? Use video ads. AdRoll supports short-form videos optimized for performance across placements.
If you want to capture attention fast, video is where it’s at — and AdRoll now fully supports video ad formats that are built for performance.
Short videos are a simple way to show your product, explain your service, or get more attention. They connect with people and help your ad get better results.
Here’s everything you need to know to get your video ads right:
· File Types: MP4, MOV
· Duration: 6–30 seconds (15–20 seconds ideal)
· Resolution: 720p minimum (1080p recommended)
· Aspect Ratios:
o 16:9 – Landscape
o 1:1 – Square
o 9:16 – Vertical (ideal for mobile)
· Max File Size: 1GB
· Captions: Many users watch with the sound off.
· Use a hook in the first 3 seconds: Grab attention immediately.
· Voiceovers: Optional but can lift engagement and brand recall.
· Stop the scroll faster
· Tell a better story in less time
· Perform well across desktop, mobile, and social
Running ads on Twitter (X) too? Repurpose your AdRoll creatives smartly:
· Use square (1:1) or vertical (9:16) formats
· Keep text short and punchy
· Use video with captions for silent viewers
· Sync your CTA and branding across platforms for consistency
Use AdRoll + Twitter together for greater reach and retargeting impact.
AdRoll ads that perform are the ones that follow the rules. When your ad is the right size, loads fast, and meets all tech specs, it shows up in the right places, at the right time, to the right people.

This collaboration will open doors for joint research, internships, and cross-border creative projects. These opportunities will help students and faculty to engage in meaningful global collaboration, exchange ideas, and contribute to innovative design solutions with real-world impact.
This international collaboration is much more than a creative industry partnership. It represents a futuristic approach towards education that bridges academics with real world needs.
If we look from the perspective of students, it provides them with direct access to international professionals, real world practices, and exposure to global creativity standards. They gain knowledge about how design functions across different cultures, and they get knowledge about how innovation in visual communication is also bound to global relevance along with local context.
From the perspective of faculty and researchers, this international collaboration opens doors for collaborative research, enrichment of the curriculum, and allows them to interact with international peers.
This creative industry partnership is unique and powerful because it connects the highly evolving and innovative creative industry with the education sector. The importance of this partnership was emphasized by Dr. Syafi’ul Anam, Dean of the Faculty of Language and Arts at UNESA:
We hope this partnership opens new avenues for students to learn directly from global professional practices, enabling them to create design works that are both competitive and deeply rooted in Indonesian character.

The world we live in is very fast paced and has truly become interconnected as we have heard throughout our lives that this world is a global village. And in this era, design is not just about creating appealing visuals; it has become more about solving problems across language, cultures and behavior of people. This makes this global education alliance between UNESA and Identify Brand Deployment Agency an important step and a futuristic approach in design education.
This international collaboration will help future designers to understand how design thinking is evolving on a global scale. Students will not just learn to use design tools; they will learn how to think critically about brand identity, cultural symbolism, user experience, and technological trends like AI in design workflows.
This initiative will also aspire the authorities to introduce changes in curriculum that will include the real-world challenges into the classrooms and will allow the students to work on them based on international market demands and in the longer run this would be beneficial as it will improve their local position in the world.
This international collaboration between UNESA’s Faculty of Language and Arts and Canada’s Identify Brand Deployment Agency is much more than a milestone; it is a signal toward building a new generation of creative professionals who can navigate and shape the global design landscape. This collaboration will serve as a bridge between academic learning and international industry practices. It empowers the students to grow culturally grounded and globally competitive.
This partnership has laid the groundwork for exciting opportunities ahead from joint research and global internships to creative knowledge exchange. It will help UNESA to grow its international presence, and this global education alliance will support its mission to equip students not just for today’s creative world, but for a future shaped by global connections and constant innovation.
