Why Ad Dimensions Matter
Running ads with incorrect dimensions leads to cropped visuals, blurry text, and wasted spend. Every platform enforces strict size requirements, and what works on Facebook won't necessarily work on TikTok or YouTube. Using the wrong aspect ratio can cause your creative to be rejected outright or displayed with ugly black bars.
This calculator gives you the exact pixel dimensions, recommended file types, maximum file sizes, and safe zone guidelines for every major ad format. Whether you are designing a Facebook Feed ad, an Instagram Story, or a Google Display banner, you will know precisely what specs to hand your designer or plug into your design tool.
How to Use the Results
Once you have your specs, set up your canvas at the exact pixel dimensions shown. Keep critical text and logos within the safe zone to avoid being clipped by platform UI elements like profile names, CTA buttons, or progress bars. Export in the recommended file format and stay under the maximum file size to ensure fast load times and platform acceptance.
