i'm building a bench seat for a window and the OCD part of me wants to make sure my 2x4 frame is 100% square.

i had a friend who said to just measure both corners diagonally and once they matched, you were good.

any tips or tricks for the novice?

Run a sting along one side. Find the center. Measure out the same distance on each side. Get someone to hold a tape measure on the the mark on the end. Hole the tape on what looks to be the center on the other end of the slab. Use a foot mark and hold a pencil or something that will make a mark and strike an arc. Get the person to hod the mark on the other end of the line and use the same measurement and strike an arc that intersects the first arc. That will be your center. From there you can measure out both ways. You can measure out from your original line and get the other side. Your frame will be perfectly square.

Too easy. OP needs to make it more complicated.

But seriously, unless you doubt your square or don't have one, why wouldn't one use their square. It's kinda good at this particular task.

Corner to corner will be good. Make sure the distances are equal if not corner to corner will not work.

There is way too much fricking going on there.

Just measure each corner to each corner and make sure they match.

3,4,5 or multiples thereof. Starting from the corner measure 3 inches or 3 ft one way, measure 4 inches or ft the other way and measure distance in between it should be 5 if the corner is square. a sq + b sq = c sq.

For a 2x4 frame a framing square will be better than measuring for square.

More accurate than trying to split 1/8" measurements on a tape.

Pythagorean theorem works great when laying out a house or fence. Way better tools for small projects.
