Ultimate Aspect Ratio Calculator Cheat Sheet for Editors, Creators & Designers

Understanding aspect ratios is crucial for creating visuals that look professional on any platform—whether it’s social media, video, or print. This cheat sheet will help you quickly identify common aspect ratios, calculate dimensions, and make sure your images and videos always look their best.

Need additional help? Use our interactive Aspect Ratio Calculator to get the exact dimensions for your next project in seconds.

What is an Aspect Ratio?

An aspect ratio is the proportional relationship between the width and height of an image or video. It’s expressed as two numbers separated by a colon, like 16:9 or 4:3. Correctly using aspect ratios ensures your visuals don’t appear stretched, squished, or cropped.

💡 Tip: If you’re unsure about what ratio to use, our Aspect Ratio Calculator can help you find the exact dimensions for your project.

How to Use This Cheat Sheet

Choose your target platform. Different platforms favor different ratios (e.g., TikTok prefers 9:16, while YouTube favors 16:9).

Calculate dimensions. Use our Aspect Ratio Calculator
 to get exact width and height for your ratio.

Adjust your content. Crop or resize images while keeping the aspect ratio consistent. For Photoshop users, check Adobe’s guide to cropping and resizing
.

Optimize for quality. Ensure your image or video resolution is high enough for the platform without being unnecessarily large. Shopify’s image size guidelines
 are perfect for this.
