No.

This is the point I'm trying to make.

The RESOLUTION of an image has NO effect on the measurement calculations......they are done by the CUSTOM SCALE that YOU set in the Measurement window and are based on the PIXELS in the image.

Try changing the RESOLUTION of 'an' image using IMAGE > IMAGE Size... WITHOUT resampling......then do your calculation with a selection.

Then change the RESOLUTION back to its original and do the same measurement with the same selection.....there will be NO difference.

On the other hand if you have an image that isn't 72ppi then it will not PRINT at the correct size.....so you need to ensure that the ppi is correct.

If the document is just totally scaled wrong and it DOES need resampling then thats a whole different question.
