About 1024x768 pixels
A 1024x768 image is landscape, with an aspect ratio of 4:3, and holds 0.79 megapixels. At 300 DPI it would print at about 3.4 x 2.6 inches (8.7 x 6.5 cm). As a JPEG it usually lands between 86KB and 173KB, depending on the picture and the quality you choose.
Where 1024x768 is used
The classic 4:3 size of older monitors and projectors, still used for some slide templates and tablet images.
- Large screen sizes make big files, so compress the result for websites and slides.
- Match the shape of the screen. A different shape either crops the picture or leaves bars.
- Landscape photos need the least cropping for wide formats.
Crop to fill or fit inside?
Crop to fill always gives exactly 1024x768 by trimming the edges that do not match the shape. Fit inside keeps the whole picture and scales it so neither side exceeds 1024x768, which can leave one side shorter. For a typical 4:3 phone photo, crop to fill removes about 0% of the picture. A 3:2 camera photo loses about 11%, a 16:9 screenshot about 25%, and a square image about 25%.
Quality and format
Check the result before you upload
Open the finished file and check three things: the picture measures 1024x768, the subject is not cut off, and the file is small enough for where you upload it. If a platform sets a size limit, run the result through the online compression tool or choose a limit such as 200KB.
A tip for this size
Phone photos are already 4:3, so little cropping is needed. Need another size? Try 800x600, 1200x675, 1280x720, the general image resizer, or browse every size preset.
Frequently asked questions
Why is my image not exactly 1024x768?
You are probably using Fit inside, which never crops. Switch to Crop to fill for exact dimensions.
How big will a 1024x768 file be?
As a JPEG, usually between 86KB and 173KB. Photos with lots of fine detail come out larger, and simple graphics smaller. Lower the quality for a smaller file.
Is 1024x768 the right size for older 4:3 screens and slides?
It is a widely used size for older 4:3 screens and slides, but platforms and agencies change their rules. Check the current guidelines before you upload.
Will a small photo look blurry at 1024x768?
If the original is smaller than this size, the tool has to enlarge it, and the result can look soft. Start from the largest version you have.
