High-quality Measuring Tape
Regardless if your DIYer is measuring the length of a bedroom or establishing the circumference of a kitchen table, he's going to need a tape measure. We're not talking about one of those flimsy $5 tools. The best tape measures cost a little more (around $25), but they're worth every penny. A good measure will reach a length of more than 25 feet, and the tape should feel firm and steady, even when stretched to its farthest lengths. The tape measure should also have a bit of flexibility so it can measure around curves and corners, too. Most DIYers already have one or more tape measures, but they could always use another.
