Crop box dimensions before you open an editor
DSLR and phone photos rarely match platform ratios out of camera. Enter pixel dimensions from file info, pick target ratio, get crop size and top-left offset.
Default 4032 x 3024 at 16:9 shows a 4032 x 2268 crop centered vertically with 378 px trimmed from top and bottom combined.
Copy exports crop size, offset, and ratio for Lightroom, Figma, or ffmpeg crop filters.

Workflow notes
Rerun when EXIF orientation changes effective width and height. Use dimensions after auto-rotate.
Video stills use the same math as photos when you read frame width and height.
Combine with PNG compression after export to hit upload limits.
Frequently Asked Questions (FAQ)
How is the center crop box calculated?
Enter source width and height plus target ratio. If source is wider than target, crop height equals source height and crop width is reduced. If source is taller, crop width equals source width and crop height is reduced. Offsets center the box.
What ratios are supported?
Presets 16:9, 4:3, 1:1, 9:16, 3:2, or custom width-to-height ratio. Default 4032 x 3024 source at 16:9 yields 4032 x 2268 crop with y offset 378 px.
Does this perform the crop on my file?
No. Output is crop width, height, and x/y offset for your editor or CSS object-position workflow. Use Image Dimension Resizer after cropping in an editor if you need export.
Why center crop?
Center crop is the default assumption when subject is framed in the middle. Manual offset for off-center subjects belongs in your photo editor using the computed size as a guide.
