Calculate aspect ratios for images, videos, and screens. Resize photos and videos while maintaining perfect proportions for social media, web design, and professional photography.
Enter either new width OR new height. The other dimension will be calculated to maintain aspect ratio.
Aspect ratio is the proportional relationship between width and height of a rectangle. It's expressed as two numbers separated by a colon (like 16:9) or as a decimal (like 1.78). Maintaining aspect ratio prevents distortion when resizing images or videos.
Pro Tip: When resizing for social media, create your content at the largest required size first, then scale down for smaller platforms. This maintains quality better than scaling up from a small image. Always check platform guidelines as they can change frequently.
16:9 is the most widely used ratio for modern displays, videos, and web content.
This happens when you resize without maintaining the original aspect ratio. Always scale proportionally.
Use 1:1 for square posts, 4:5 for portrait posts, and 9:16 for Stories and Reels.
