@sheetmetalsamurai: Three Ways to Measure an Inside Wall (Without Guessing) Most tape measures aren’t great inside corners — so here are three legit ways to get an accurate inside wall measurement. Method one: add the width of the tape body itself. A lot of tapes actually print that number right on the side. Method two: use a credit card and a paper clip on the tape to bridge the gap. Method three: measure 10 inches off one wall, mark it, then measure from the other wall to that mark and add ten. No special tools. No eyeballing. Just clean, repeatable measurements. #measuringtips #tapemeasure #diytips #carpentry #carpentrytips
