Every creator knows the frustration: you finish a perfect photo, then realize Instagram wants 1080×1080, TikTok wants 1080×1920, LinkedIn wants 1200×627, and Amazon's main image has to be exactly 2000×2000 or your listing gets penalized.
Instead of Googling each spec and opening an image editor every time, I keep a cheat sheet of the 8 dimensions I actually use. Here it is.
The 8 image dimensions every creator needs
| Platform | Use case | Size (px) |
|---|---|---|
| Instagram Post | Feed post | 1080 × 1080 |
| Instagram Story | Story / Reel cover | 1080 × 1920 |
| TikTok | Video thumbnail / cover | 1080 × 1920 |
| YouTube Thumbnail | Video thumbnail | 1280 × 720 |
| LinkedIn Post | Article / feed image | 1200 × 627 |
| Facebook Cover | Page cover photo | 1640 × 924 |
| Amazon Main Image | Product listing | 2000 × 2000 |
| Etsy Listing | Product photo | 2000 × 2000 |
These are the specs that actually matter. Everything else is a variant you'll rarely need.
Why resizing manually is a waste of time
Open an editor → import the image → find the canvas settings → enter the new dimensions → drag the image to fit → export → repeat for the next platform.
For one photo across five platforms, that's five separate exports. Multiply that by ten products a day, and you've just lost an hour.
The faster way: browser-only resizing
I built imgsize specifically for this workflow. It runs entirely in your browser — your photos never leave your device.
Here's the 10-second process:
- Open imgsize
- Pick the platform preset (Instagram, TikTok, LinkedIn, Amazon, Etsy, etc. — 70+ built in)
- Drop your image
- Download the perfectly sized result
No upload. No login. No watermark. No waiting for a server to process your file.
The best part: if you need the same image for multiple platforms, you can export them all in a ZIP — one drop, multiple exact sizes, done.
Stop guessing dimensions
Bookmark this post or save the imgsize link next time you're about to publish. The goal isn't to learn every spec by heart — it's to stop caring about the math and just get the right output.
What platform dimensions do you find yourself looking up most often? Drop it in the comments and I'll add it to the preset list.
