600 × 400 pixels at a glance
600 × 400 pixels is a landscape image 600 pixels wide and 400 tall: 240,000 pixels in total (0.24 megapixels), with a 3:2 aspect ratio (1.5:1). It is the native shape of most DSLR and mirrorless camera photos; a phone photo loses a strip at the top and bottom.
It is a full-width web size that fills a phone screen or a blog column without looking soft. On this page our three test files came out at 25.6 KB to 125.1 KB as JPG and 4 KB to 102.1 KB as WebP.
Where 600 × 400 is asked for, and whether it fits
Facebook link previews
Meta uses the larger link-preview layout for images of at least 600 × 315 pixels and asks for an aspect ratio as close to 1.91:1 as possible so the full image shows without cropping. 600 × 400 is wide enough for the large layout, but at 3:2 it is taller than 1.91:1, so Facebook trims the top and bottom of the preview. Use 1200 × 630 when the whole image must be visible.
Instagram posts
Instagram keeps photos between 320 and 1080 pixels wide at their own resolution when the aspect ratio is between 1.91:1 and 3:4. 3:2 is inside the range, so a 600 × 400 image is posted uncropped, just at a little over half the feed width.
600 × 400 in numbers
Worked out from the pixel size. The crop rows assume the page's default "Crop to fill" setting.

How to make a 600 × 400 image
Add your images
Drop one or more JPG, PNG or WebP files. All of them get the same size and format; you can move the crop for each one.
Choose how to reach 3:2
Keep "Crop to fill" for a full frame with nothing stretched, and drag the preview so the subject stays inside it. Switch to "Fit inside, pad" when nothing may be cut off, such as a wide logo.
Pick the format
JPG is accepted everywhere. WebP was smaller for most of our test files at this size, if the site accepts it; PNG keeps transparency but makes the largest files.
Download and check
The file name ends in -600x400, and the results panel shows the exact pixel size and KB so you can compare them with the form before uploading.
What this page produced from our test files
We ran three fixed test files through this page in headless Chrome 129.0.6668.29 on 2026-10-19, with the default "Crop to fill" setting. Sizes are the bytes of the downloaded files. The test files are generated from a fixed seed so anyone can repeat the run; they are not customer photos. WebP was smaller than JPG for all three files, by 18% to 84%.

Before you upload a 600 × 400 image
- 3:2 is the native shape of most DSLR and mirrorless camera photos (6000 × 4000, for example), so camera files shrink to 600 × 400 without any crop. Phone photos are 4:3 and lose about 11% of their height.
- Printed at 300 DPI, 600 × 400 pixels is only 2 × 1.33 inches. For a 6 × 4 inch print you need 1800 × 1200 pixels.
Frequently asked questions
What aspect ratio is 600 × 400?
3:2, or 1.5 to 1. Any size with the same ratio, such as 1200 × 800, has the same shape and can be resized to 600 × 400 without cropping.
How many KB is a 600 × 400 image?
In our tests, 25.6 KB to 125.1 KB as JPG and 4 KB to 102.1 KB as WebP. Without compression it would be 703.1 KB. Noise, text and fine texture make files bigger; flat graphics make them smaller.
How big does 600 × 400 print?
2 × 1.33 in (5.1 × 3.4 cm) at 300 DPI, or 4 × 2.67 in (10.2 × 6.8 cm) at 150 DPI. DPI only changes the print size, not the pixels, so the file is the same either way.
