Ask HN: What is a good way to screenshot a perfect square?

1 pointandrewfromx3 comments

This happens to me all the time, I command+shift+4 to get a crosshair cursor on mac and then I can draw any shape I want. But trying to get a perfect 50x50 or 100x100 is very hard. I end up with 52x49 or 101x103. I know there is snagit from techsmith but is there anything free that does this?

Adjusting the screenshot area by dragging the center at a side helps quite a bit, as it allows you to adjust the width without risking also adjusting the height (or vice versa)

The CLI also is an option for some use cases. See man screencapture.

oh it's command+shift+5!!! wow that's great thank you!

You can make the screenshot square bigger than you need it to be, then click on the screenshot when it appears in the bottom right. Click the edit button at the top, then click the crop icon. Hold shift and drag the corner.
