Social Media Image Sizes 2025: The Complete Cheat Sheet
Every social platform crops, resizes, or rejects images that don't match its expected dimensions. Upload the wrong size and your carefully designed graphic gets awkwardly cropped, your face ends up cut off in a profile photo, or your cover image gets visibly pixelated after the platform stretches it. Below is the exact pixel dimensions every major platform expects right now, plus how to resize correctly.

Skip the math — resize to the exact size you need
Open the Free Resize Tool →How to resize an image to an exact size
- Open a free image resizer.
- Upload your image.
- Either pick a preset size from the list (many tools include the most common social media dimensions directly), or enter your own exact width and height.
- If you want to preserve the original proportions to avoid stretching, keep "lock aspect ratio" enabled.
- Download the resized image and upload it directly to your platform of choice.
A note on aspect ratio vs. exact dimensions
If your source image doesn't already match the target aspect ratio, simply typing in the exact target width and height (without locking aspect ratio) will stretch or squash the image — which usually looks distorted. The better approach is to crop the image to the correct aspect ratio first, then resize to the exact pixel dimensions afterward.
Frequently asked questions
What happens if I upload an image that's the wrong size?
Most platforms will automatically crop or scale your image to fit their required dimensions. This often crops out important parts of the image (like faces near the edges) or causes visible quality loss if the platform has to upscale a smaller image.
Should I resize before or after compressing an image?
Resize first, then compress. Resizing down reduces the total pixel count, which means compression has less data to work with and can achieve a smaller file size more efficiently at the same visual quality.
Do these social media image sizes change often?
Platforms occasionally make small adjustments, usually when redesigning their interface. The dimensions above reflect current 2025 specifications, but it's good practice to verify against the platform's official help documentation before a major campaign.
What's the best file format for social media uploads?
JPG works well for photos and is widely accepted everywhere. PNG is better when you have text overlays, logos, or graphics with sharp edges, since it avoids the slight blurring that JPG compression can introduce around fine details.
