yes, and print size can impact how a print is agitated, speed of developer across the paper etc. There's the maths and then using the Mk I Eyeball for any adjustments required.

PS On the comment earlier about going from 8x10 to 20x16 and running out of stops, no way. If using F5.6 at 8x10, you'd be on F11 at 20x16. I never use area, but caculate new exposures based on height between the easel and the lens rim.
