Why is the right pixel size not enough?
Most size guides give you a list of numbers and stop, which is the less useful half. A correctly sized image still gets cropped, covered and re-encoded on its way to a viewer. Three things happen to every upload. Platforms display the same image in several places with different shapes — a feed, a profile grid, a search result — and take a different crop for each. They draw their own interface over it: usernames, captions, action rails, duration badges. And they re-encode, almost always as JPEG, which is why fine text and flat colour often look worse after posting than before. The question worth answering is not what size an image should be, but which region of it survives every place it will appear. Each preset page below documents that for its specific platform.
Fill or fit, and when each is right
Every preset offers two modes and they solve different problems. Fill scales the image until it covers the whole frame and trims the overflow from the centre outward, which is correct for photographs where losing some background is harmless and a full-bleed result is what you want. Fit scales the entire image until it sits inside the frame and pads the remaining space, which keeps every pixel visible. Fit is the right choice for artwork, screenshots, infographics and product shots on a plain background, where cropping would remove the thing you are trying to show. The common mistake is using Fill on a wide landscape photograph destined for a vertical frame and wondering where most of the scene went — for that case, either switch to Fit or choose a preset whose shape matches the composition.
Resolution, density and print
The most frequent sizing error is exporting at the dimensions something appears at on screen. Modern phones and laptops pack two or three physical pixels into each CSS pixel, so an image displayed 400 pixels wide needs roughly 800 pixels of real data to look sharp. Exporting at display size is why images look soft on high-density screens. Print follows different arithmetic and is stricter. Print quality is measured in dots per inch, 300 dpi is the commercial standard, and a 6-inch-wide print therefore needs 1,800 pixels of width. An image that looks perfect on screen at 800 pixels will look visibly soft printed at any reasonable size. Going the other way, uploading far larger than a platform stores does not help either. Instagram caps feed images at 1080 pixels wide and YouTube stores thumbnails at 1280×720, so an oversized upload just adds a server-side downscale on top of the platform's own compression — two lossy steps instead of one.
Frequently asked questions
Are these the official platform sizes?
- Yes, these are the dimensions each platform currently recommends or displays at. Platforms change them periodically, so each preset page notes when its figures were last checked.
Will resizing crop my image?
- Only in Fill mode, which trims the overflow to cover the frame. Fit mode scales the whole image inside the frame and pads the remaining space instead.
Are my images uploaded?
- No. Resizing runs on a canvas inside your browser. Nothing is transmitted, and the tool keeps working with the network disconnected.
Should I upload the highest resolution I have?
- No. Platforms cap what they store, so uploading larger adds an extra downscale on top of their compression for no visible benefit.
What size do I need for printing?
- Multiply the printed size in inches by 300. A 6-inch-wide print needs about 1,800 pixels of width to look sharp.
Why does my image look soft on my phone?
- Most likely it was exported at display size. High-density screens need roughly double the pixel dimensions of the space the image occupies.
Can I resize to a custom size instead?
- Yes — the image resizer takes any width and height you enter, with an optional aspect-ratio lock.
