# Will PVA glue add some thickness to two and more pieces of plywood?

I have 5' x 5' sheets of baltic birch plywood having a thickness close to 3/4" at 23/32" so it's missing 1/32".

I want to glue 4 pieces together using yellow PVA glue.

I'm currently designing a multi-station workbench with 3"x3" legs (3/4 x 4 = 3") but since the material is 23/32 the total thickness would be (without gluing) 23/32 x 4 = 92/32 = 2 7/8 so I'm missing 1/8 !

However does glue add some thickness between the 4 pieces? I'm counting on the fact that it would result in getting close to an overall thickness of 3"... am I right?

Thanks!

## Update:

Trying to fit posts with rails, all of them consisting of 4 pieces joined together. Each piece, before being glued together, is cut with the necessary shape for either a mortise or tenon.

This match is easy:

This one I am not sure:

• The thickness of a PVA glue layer should be negligable, assuming you used a sanw amount of glue and clamped the pieces while the blue dried. Aug 29, 2016 at 13:28
• Why do the legs need to be exactly 3" square? Work with the size they end up with, whatever it is. If you were doing this in solid wood due to planing or sanding differences you could have maybe a 1/64" discrepancy between legs and it wouldn't make any real difference to the finished piece.
