12X16 developing trays

[Old Jim]

Here is a photo of an 8x10 sheet of paper in a Paterson 8x10 tray. You may or may not want more room around the edges depending on your method of agitation.

Looks kinda like a close fit to me. If I only do single sheets it should be fine. I will probably get one and try it.
Thanks for all the comments.
