Social Media Image Sizes 2025: The Complete Reference Guide
Every dimension you need for every major platform, updated for 2025. Bookmark this page and never guess at image sizes again.
Why Correct Image Sizes Matter
Social media platforms aggressively resize and recompress every image you upload. If your source image does not match the platform's expected dimensions, it will be stretched, cropped, or padded — and then compressed at a lower quality setting. The result is a blurry, awkwardly framed image that undermines the content you worked to create.
Correctly sized images display sharply, fill the intended space, and survive platform recompression with minimal quality loss. Studies consistently show that posts with high-quality visuals receive 2-3x more engagement than those with pixelated or poorly cropped images. Taking thirty seconds to resize before uploading pays for itself immediately.
Use our Image Resizer to hit exact pixel dimensions and our Image Cropper to frame your subject perfectly — both run entirely in your browser.

Pro tip: Use portrait (4:5) posts whenever possible. They occupy more vertical space in the feed, which increases dwell time and engagement. Keep important content away from the top and bottom 200 pixels of Stories and Reels — that is where the UI overlays sit.
Feed Post Image

1200 x 628 px
Facebook cover photos are notoriously tricky because desktop and mobile crop differently. Design with the key content in the center 640x312 safe zone to ensure it looks correct on both. Upload as PNG for text-heavy covers to avoid JPEG artifacts.
Twitter / X
In-Stream Photo
16:9 ratio displayed in timeline
1600 x 900 px
Header / Banner
3:1 ratio, crops vary by device
1500 x 500 px
Profile Photo
Displayed as circle, 400px recommended
400 x 400 px

X supports images up to 5MB for photos (PNG, JPEG, WebP) and 15MB for GIFs. For the sharpest results, upload at exactly 1600x900 or 1200x675 — these match the platform's preferred 16:9 display ratio. Images with different aspect ratios will be center-cropped in the timeline.
YouTube
Video Thumbnail
16:9 ratio, under 2MB
1280 x 720 px
Channel Banner
Safe area for all devices: 1546x423 center
2560 x 1440 px
Profile Photo
Displayed at 98x98, upload larger for quality
800 x 800 px
YouTube thumbnails are arguably the most important image on the platform — they directly determine click-through rate. Use bold, high-contrast designs with faces (if applicable) and large text that is readable at small sizes. Avoid small details; thumbnails are often displayed at just 168x94 pixels on mobile.
Feed Post Image
1.91:1 or 1:1 ratio recommended
1200 x 628 px
Personal Cover / Banner

TikTok
Video / Photo Post

Standard Pin

Pinterest favors tall, vertical images because they take up more space in the masonry grid feed. Pins with a 2:3 aspect ratio consistently outperform square or landscape images. Avoid ratios taller than 2:3 as Pinterest will truncate them in the feed.
Tips for Cross-Platform Images
Start with the largest size
Design at the highest resolution any platform requires, then resize down for each platform. Scaling up from a smaller image always produces blurry results.
Keep subjects centered
Different platforms crop at different ratios. If your key content sits in the center of the frame, it will survive any crop. Use our Image Cropper to preview how different aspect ratios affect your composition.
Account for UI overlays
Stories and Reels on Instagram and TikTok overlay usernames, captions, and action buttons on the top and bottom of the screen. Keep text and faces in the middle 60% of vertical content.
Export as JPEG at quality 85-90
Every platform re-compresses uploads. Starting with a high-quality JPEG gives the platform's encoder more data to work with, resulting in a better-looking final image. PNG files are fine for text-heavy graphics but their larger file size provides no benefit after platform recompression.
Test on mobile first
Over 80% of social media consumption happens on mobile devices. Always preview your images on a phone screen before publishing. Text that looks crisp on a 27-inch monitor may be illegible on a 6-inch phone.
Stay Up to Date
Social media platforms update their image specifications regularly. We keep this guide current as changes roll out. Bookmark this page for quick reference, and use QuickPix's Image Resizer and Image Cropper to prepare your images in seconds — free, private, and entirely in your browser.
