Image Size for Social Media – Instagram, Facebook & More

Upload the wrong size and Instagram crops your face out of the frame. Post a 1200 × 630 px image on a Story and it gets stretched. This free social media image size tool resizes your image to the exact dimensions for every platform — 1080 × 1080 px for Instagram square, 1080 × 1920 px for Stories and Reels, 1280 × 720 px for YouTube thumbnails — in one click, no upload required.

No upload, no account, 100% private. This tool works directly in your browser using HTML5 canvas technology — your image is processed locally and never sent to any server.

Tip: If your image doesn't match the required dimensions, use the image resize tool before applying platform presets. After resizing, you can also optimize the image for web or reduce the file size for faster uploads.


How Social Media Image Sizing Works

Every social media platform enforces specific image dimensions and aspect ratios for each post type. When you upload an image that doesn't match the expected ratio, the platform automatically crops it — often cutting off important parts of your image without warning.

Aspect ratio is the proportional relationship between width and height. Instagram posts accept ratios between 4:5 (portrait) and 1.91:1 (landscape). Anything outside that range gets cropped to the nearest accepted ratio. A 16:9 landscape photo uploaded to Instagram as a feed post will have its sides trimmed to fit 1.91:1 — losing around 10% of the image width on each side.

This tool works directly in your browser using HTML5 canvas technology. Select your target platform, and it crops and resizes your image to the exact pixel dimensions the platform expects — giving you full control over what gets shown.

Example: Instagram Image Sizes in Practice

Instagram is the platform where image sizing causes the most confusion. Here are the three core feed formats and when to use each one:

Square Post
1080 × 1080
1:1
Product shots, logos, quotes. Most consistent across devices.
Portrait Post
1080 × 1350
4:5
Portraits, fashion, food. Takes up 35% more screen space than square.
Story / Reel
1080 × 1920
9:16
Full-screen vertical. Keep key content in center 1080 × 1420 px safe zone.

A 4000 × 3000 px landscape photo uploaded directly to Instagram as a feed post gets cropped to 1.91:1 — Instagram trims the top and bottom. Resize it to 1080 × 1080 px or 1080 × 1350 px first using the social media image size tool above and you decide exactly what gets shown.

The 4:5 portrait format (1080 × 1350 px) is widely considered the best-performing feed format on Instagram because it takes up the most vertical screen space — giving your image more visibility before users scroll past it.


When to Use and When Not to Resize for Social Media

Not every image needs to be resized before posting. Here is when it matters most:

SituationResize?Why
Posting to Instagram feedYesInstagram crops anything outside the 4:5 to 1.91:1 ratio range. Resize first to control composition.
Creating YouTube thumbnailsYesThumbnails must be 16:9. Wrong ratio results in black bars or cropping at different display sizes.
Uploading to PinterestYesTall pins (2:3) outperform square or wide formats. Resize to 1000 × 1500 px for best visibility.
Sharing photos in a chat or messageNot neededMessaging apps display images at original proportions. No cropping enforcement.
Emailing an image as attachmentNot neededEmail clients don't enforce aspect ratios. Only file size matters for attachments.
Posting to X (Twitter)OptionalX displays a cropped preview in the timeline but shows full image on click. Resizing improves the preview crop.

Frequently Asked Questions

What is the correct image size for Instagram?
Instagram supports three main feed formats: square at 1080 × 1080 px (1:1), portrait at 1080 × 1350 px (4:5) and landscape at 1080 × 566 px (1.91:1). Stories and Reels use 1080 × 1920 px (9:16). Use the social media size tool above to resize your image to any of these formats instantly.
What image size should I use for Facebook?
For Facebook feed posts, use 1200 × 630 px (1.91:1). Facebook Stories use 1080 × 1920 px. Cover photos are 851 × 315 px on desktop. Facebook automatically crops images that don't match the recommended ratio, so resizing before upload gives you full control over composition.
What is the best image size for YouTube thumbnails?
YouTube thumbnails should be exactly 1280 × 720 px at a 16:9 aspect ratio. The maximum file size is 2 MB. YouTube displays thumbnails at many sizes across the platform — using 1280 × 720 px ensures your thumbnail looks sharp everywhere from mobile search results to desktop browse pages.
What size should TikTok videos and images be?
TikTok uses a 9:16 vertical format. The recommended size is 1080 × 1920 px for both videos and photo posts. Horizontal (16:9) and square (1:1) formats are supported but vertical content consistently performs better since it fills the full screen.
Why does Instagram crop my images automatically?
Instagram crops images that fall outside its accepted aspect ratio range — between 4:5 (portrait) and 1.91:1 (landscape). If your image is taller than 4:5 or wider than 1.91:1, Instagram trims the edges automatically. Resizing to the correct dimensions before uploading prevents this. For print-related sizing questions, see our DPI checker tool.
What is aspect ratio and why does it matter for social media?
Aspect ratio is the proportional relationship between an image's width and height (e.g. 16:9, 1:1, 4:5). Each social media platform enforces specific ratios per post type. Using the wrong ratio results in automatic cropping, black bars or stretched images. Matching the platform's expected ratio before uploading gives you full control over how your content appears in the feed.
