How to Read a Tape Measure?

In other words, 1 = 1, 2 = 2, etc. Between those numbers are a number of smaller marks, each separated by a fraction of an inch. The marks in the center of the inch denote a measurement of 1/2″, while those on either side of it denote measurements of 1/4″ and 3/4,” respectively.

Both metric measurements (centimeters and millimeters) and imperial measurements (inches and feet) are available on tape measures, and both have easy-to-understand divisions into smaller markings.

How should I understand a cm tape measure?

Find the zero mark on the tape measure, which is typically at the end but may also be indicated by a “0” or a notch.

After that, use the tape measure to take the measurement of the object by aligning its end with the zero mark.

Look at the number on the tape measure that is closest to the end of the object you’re measuring to determine the measurement in centimeters, which are indicated by the numbered marks on the tape measure. Each centimeter is marked with a number, such as 1, 2, 3, and so on.

Step 1: Recognize the Fundamentals of a Tape Measure

A tape measure consists of a long, flat strip of material, usually metal, with markings along its length. The markings indicate measurements in either inches or centimeters. Before you can begin reading a tape measure, it’s important to comprehend its basic components.

Step 2: Determine the Units of Measurement

As indicated by markings along the top edge of the tape measure, with centimeters on one side and inches on the other, make sure you’re using a tape measure that measures in centimeters (cm) rather than inches.

Step 3: Read the entire centimeter

To read the measurement in centimeters, simply look at the number closest to the end of the object you’re measuring and read the whole number. For example, if the end of the object lines up with the 15 cm mark, the measurement is 15 cm. The largest markings on a tape measure are the whole centimeters. These are the numbers that are evenly spaced along the length of the tape measure.

Step 4: Read the millimeters

To read the millimeters, simply count the number of lines between the whole centimeter mark and the end of the object. For example, if the end of the object lines up with the third line after the 15 cm mark, the measurement is 15.3 cm. After the whole centimeters, there are typically smaller markings that indicate millimeters. Each millimeter is represented by a thin line between the whole centimeters.

Step 5: Adding or subtracting fractions of a centimeter

Each millimeter is divided into 10 parts, so each part represents 0.1 cm; however, sometimes the end of the object won’t line up exactly with a whole centimeter or millimeter mark. In this case, you can estimate the measurement by adding or subtracting fractions of a centimeter. For instance, if the end of the object lines up roughly halfway between the 15 cm mark and the 16 cm mark, you can estimate the measurement as 15.5 cm (15 cm + 5 x 0.1 cm).

It may take some time to get used to reading the markings on the tape measure, but with a little perseverance and focus on the details, you’ll soon be able to measure with confidence.

The measuring tape is a crucial tool for getting accurate measurements and in this article, we’ll show you how to read a measuring tape in inches. Measuring tapes are frequently used to measure lengths and distances for various purposes, including sewing, woodworking, construction, and many others.

How do you read an inch measuring tape?

The blade, a long, narrow metal strip that extends from the case, the hook, a small metal piece at the end of the blade that latches onto an object for measurement, and the case, which holds the blade and hook when the tape is not in use, make up a standard measuring tape.

Sizes in Inches

The longest lines on a measuring tape represent inches and are typically numbered in multiples of two; the shorter lines between the inch lines represent fractions of an inch and are typically numbered in eighths, sixteenths, or thirty-seconds. The inch scale is the most frequently used scale on a measuring tape.

A Whole-Inch Reading

The longest lines on a measuring tape marked with numbers, each of which represents one inch, are where you should look to read whole inches. For instance, if you wanted to measure a length of four inches, you would find the line marked with the number 4.

Using fractions of an inch to read

You can read fractions of an inch by looking at the smaller lines between the inch lines, which are marked with fractions like 1/8, 1/16, or 1/32. To find the fraction, you need to count the number of lines between the inch lines. For instance, if you want to measure a length of four and a half inches, you would locate the line marked with the number 4 and then count two lines beyond that.

Tenths of an inch reading

Some measuring tapes have markings for tenths of an inch, which are typically smaller than the fraction lines and are frequently marked with a decimal point. To read tenths of an inch, you need to count the number of lines between the inch lines and then divide by ten. For instance, if you want to measure a length of four and two-tenths inches, you would locate the line marked with the number 4 and then count two lines beyond that.


Reading a tape measure is one of the most basic skills any Pro or DIYer needs. Whether you’re measuring something for construction or trying to figure out how wide your new refrigerator opening is, a good understanding of a tape measure is an essential skill that you should always have on hand.

Tape measures come in both Imperial Units (inches and feet) as well as metric measurements (meters and parts of meters, such as centimeters). They can also have markings for truss lengths and stud intervals, which are important features that make them a valuable tool for any professional.

The best way to read a tape measure is by following the markings. They usually start with number markings for inches, and then foot marks follow. Some tape measures have a special marking for each foot, which is helpful when laying out studs and joists.

Another common marking is the half-inch mark, often the second biggest number on a tape. This is the same principle as reading an inch; only it’s half the distance from the biggest marking to the next biggest.

In addition to the big numbers, most tapes have smaller markings between the big ones that represent quarter and half inches. You can think of these as the spaces between the big and small inch markings on a tape, and they’re useful for giving you a better idea of where to read a measurement.

1/32 measure is measured by calculating how many marks are left to a full inch of the length of a given measure can be.

One instance where it’s beneficial having the 1/32 tape measure is to measure stairs. When stair risers aren’t correct by even one-quarter in an inch, the mistake can be compounded over the steps and causes the entire stairway to be too narrow or tall.

What is the diamond in a tape measure? | How can you make use of this unique feature?

The diamond in a tape measure could be one of the most secretive secrets. We will explain how it works and what it can do.

You may be asking what exactly is the diamond on tape measures?’ If you’ve ever noticed the tiny marks along the top of the device.

A diamond has been a part of the tape measure since we can remember. It is among the marks that you’ll find on the measurements. However, there are many different tape measures, and not everyone is created equal.

We will explain what diamonds represent and the other things you need to look for when using a tape measure to maximize the use of the tool.

What is the diamond in the tape measure?

It is common to find an elongated black diamond at the top of the tape measure at intervals of regularity. On a U.K. tape measure, the diamond will usually be located at intervals of 19.2 inches across the tape.

This diamond is an inscription for joists generally placed by this much within U.K. structures. Joists are generally located in 19.2-inch intervals because of the large number of boards like plywood, having eight feet (96 inches) lengths.

If you divide it by 5, it gives you 19.2 inches. This works as a great spot for the middle of the joists. The DeWalt tape measurement(opens in a new tab) is a high-quality illustration if you plan to utilize diamonds on your next job.

To confuse the matter, Some tape measures contain a diamond at intervals of 16 inches, as shown in the following image. This measurement is commonly used by the U.S. If you’re trying to learn how to construct a partition wall inside, The U.K. space is measured using millimeters.

To make matters more confusing, It’s important to note that the mark isn’t always the diamond. Sometimes, it’s an arc instead.

What do the red boxes that measure 1/32 inches actually do ?

Some tape measures come with diamonds every 16 inches. This is usually accompanied by the red box. In certain instances, there may only be an orange box (with the number) with 16-inch gaps. This is the most common measurement of studs on a stud wall within the U.S.

In the U.K., the norm for a wall gap between studs is 400mm. It is almost 16 inches or 406 mm; however, it is not the same. Therefore, if you’re creating a stud wall within the U.K., it is best not to be used it.

What’s the function of the metal edge of the tape measurement?

The metal edge on tape measures – evident after the tape has been fully retractable is called a hook. It is a good idea to place it on the edge of a surface, then pull out the tape measure to take measurements and make marks.

Some tape measures feature the term nail grab, an indentation or hole that can grab screws or nails in need. This is a great option when measuring from the center of a stud or joist.

Some have teeth with small sizes to make a mark, even when you don’t have a pencil. If the item doesn’t have teeth, you can use your hook’s edge to create marks.

What is the reason why the hook at the tape’s end is missing?

You’ve probably noticed that the hook at the end of the tape is loose. This isn’t an error in manufacturing and is designed to be that way. The tape measure measures short by a 16th of an inch, that is, the length of the hook. This ensures you have accurate readings when measuring the interior or the outside of an object.

When measuring the inside of a wall, such as when you’ve completed the painting of the windows and want to measure for blinds, the hook is pulled into the tape to fill the 16/16 inch gap. If you are measuring the exterior of an object, the tape pulls out an additional sixteenth of an inch to provide an exact measurement.

What other marks on tape are there other marks to be looking for?

The most common feature of every tape measure can be seen in the length measurement. This is typically located near the top of the tape so that you can easily see it, and usually, it’s in feet and meters.

Some other marks you will find on a tape generally indicate the quality. A CE mark indicates that the tape complies with E.U. standards. Roman numerals signify accuracy, with level 1 being the highest.

If your tape measure does not include one, it’s not been examined to ensure it meets an acceptable level of accuracy. However, most brands include them, and tapes that don’t have them are adequate for DIY projects like building walls.
