I am a portrait photographer and need a square crop... Is there a way to crop in photoshop and leave headroom with an exact number of pixels? eg. 170 pixels of headroom

Actions and scripting

Try this :

Crop to 1024 (or whatever your wanted width)/1024(or whatever your wanted width)-170 = 1024(or whatever your wanted width)/854 without erasing cropped pixels

Go to canvas size and add 170 px to the top

And you get a 1024/1024 with 170 on top

Could you please post screenshots with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible for the image and its intended end-result?

What are the final pixel dimensions supposed to be?

Turn on rulers.

Right click inside a ruler and set it to pixels.

Drag grid origin to the top of the subjects head.

Make a new guide at -170px

Snap top of crop bounding box to that guide.

Yes, creating the headroom at a fixed px value shouldn't be the issue, but how will you crop to square? Using a constrained rectangular selection marquee tool or using the crop tool with a 1:1 ratio?

Please attach before/after example images, you can redact the face area to retain client privacy.

If the Select > Select Subject command can consistently identify the top of the head correctly, then this can be semi-automated using an interactive action.
