## What is a Tape Measure

A tape measure is a roll of metal tape with measurement markings on and is used for measuring. Usually the tape is yellow and rolled in a plastic case. Tape measures are commonly used in construction, architecture, building, home projects, crafts, and woodworking. They usually come in lengths from 6 feet to 35 feet long. Tape measures may have measurements in imperial and metric, imperial-only, or metric-only.

Tape measure markings represent the fractions of an inch. Each large tick represents one inch (1″) and the ticks between represent the following fractions: 116“, 18“, 316“, 14“, 516“, 38“, 716“, 12“, 916“, 58“, 1116“, 34“, 1316“, 78“, and 1516“. To read a tape measure find the number next to the large tick, and then find how many small ticks past it the measurement is. Add the number next to the large tick with the fraction to get the measurement. eg. if your 5 ticks past the number 4 tick then the measurement is 4 516“.

### What are the Tape Measure Markings

In order to read a tape measure you need to understand what all of the little markings mean. The large ticks are 1″ apart and the small ticks are fractions of an inch.

The ticks in the middle of the inch markings are half-inch markings, and there is 12” between each inch marking and half-inch marking.

The ticks between the inch markings and half-inch markings are quarter-inch markings. There is 14” between the one inch marking and the quarter-inch marking. There is 14” between each quarter-inch marking and the half-inch marking.

The second smallest ticks are eighth-inch markings and there is 18” between the eighth-inch markings and the quarter-inch markings and one-inch markings.

The smallest ticks on a tape measre are sixteenth-inch markings. There is 116” between each marking on the tape measure.

## Tape Measure Tips and Tricks

### Using the Sliding Hook

The hook on a tape measure usually slides just a little bit. This is by design to account for the thickness of the hook on the end. This allows the tape measure to be accurate when hooking onto a surface and also when butting the end up to a surface. Be mindful of tape measures that do not have a sliding hook as they will not be as accurate.

### Using the Nail Grip on the Hook

The hook on a tape measure often has a small hole or groove in it. This is to allow hooking the hook on a nail or screw so it doesn’t slide of when making long measurements.

### Using the Sides of the Hook

Some tape measures have large hooks that can be used to grip surfaces on the side of the hook. Using these can improve the gripping ability of the hook and improve the accuracy of measurements since the tape measure will not need to be twisted to read the markings.

### Using the Tape Lock

Almost all tape measures have a lock that will keep the tape measure from recoiling. This is useful if you need to take tension off of the tape measure or if you need to set the tape measure down while it is extended.

## Choosing a Tape Measure

There are many tape measures on the market and many serve very different purposes. When choosing a tape measure consider what you’ll be using it for, how long you need it to be, and how much you’d prefer to spend.
