Enter your image dimensions or select a platform to find the perfect size for social media.
Each social media platform displays images at specific dimensions. Using non-standard sizes forces platforms to crop, stretch, or letterbox your images, resulting in an inconsistent brand appearance. A 1080x1080 square image displays perfectly across Instagram, Facebook, and LinkedIn feeds.
Uploading images at the exact display size eliminates unnecessary data. A 4000x3000 photo scaled down to 400x300 in the browser wastes bandwidth and slows page loads. Use the calculator above to find the exact dimensions for each platform, then resize to match.
Aspect ratio describes the proportional relationship between width and height (e.g., 1:1 for square, 16:9 for widescreen). Two images with different pixel dimensions can share the same aspect ratio. Use our calculator to find which platform presets match your image's aspect ratio.
Starting with an image that is smaller than the target dimensions means the platform must upscale it, causing blurriness and pixelation. Always upload images at or above the platform's recommended resolution. Our dimension calculator shows you the minimum size for each media type.
1080 x 1080 pixels (1:1 square) is the most universally supported size. Instagram, Facebook, LinkedIn, and X/Twitter all display square images natively. It is the safest choice for cross-platform posting.
Divide both width and height by their greatest common divisor. For example, 1920x1080 simplifies to 16:9 (1920/120 = 16, 1080/120 = 9). Use this calculator to find which standard aspect ratio matches your image dimensions.
For web, 72 DPI is standard and 1920px on the longest side is sufficient for most displays. For print, 300 DPI is required. Use the dimensions above as a starting point and always verify with your specific platform's requirements before uploading.
