Always ensure that the tang is fully extended when hooked onto an edge. To account for this, the tang slides out 1/16 of an inch when it is hooked onto an object, allowing the true measurement to be taken. However, this would leave you 1/16 of an inch short for objects that are measured from the outside edge, such as a deck board.

So for measurements taken from the inside edge of an object, such as measuring the length of a wall from corner to corner, the tang slides back against the blade and the metal of the tang is added to account for the “missing” 1/16 of an inch. The first inch on a tape measure is actually short by 1/16 of an inch, because the metal on the tang is exactly 1/16 of an inch. Photo: The true zero hook feature will keep measurements accurate. This lets you quickly identify joists without using a stud finder, helpful when nailing floorboards. Joist measurement: Black diamonds located every 19 3/16 inches indicate on-center joist spacing.Keep in mind that the second stud in a wall is installed 16 inches from the end of the wall, not from the center of the first stud. So if, for example, you’re installing baseboard trim, you can lay the measuring tape across the wall and use the red squares to locate the studs behind the drywall. Stud measurements: Red squares every 16 inches indicate on-center wall stud spacing.Understand these important additional measurements. It is not indicated by a number or fraction, but simply by the smallest line on the metric side of the blade, with every fifth millimeter line being slightly longer to indicate the halfway point between centimeters. Millimeter or 1mm: The smallest metric measurement on the blade is the millimeter.This measurement can be found at every 10th millimeter marking. Centimeter or 1cm: This measurement is indicated by the longest line on the metric side of the blade and a large number.This measurement is located at every 10th centimeter line. Decimeter or 1dm: The one-decimeter marking is normally shown at a red numeral of 10.On some tape measures, the centimeters will begin at one following the meter marking. Meter or 1m: The one-meter marking is located at the one 100th centimeter marking or 10th decimeter marking.

Don’t say, “duh!” Plenty of DIYers and even some experienced professional carpenters may not be aware of all of the information on a retractable metal tape measure.
