How to Measure Height

A height measurement may be required for health reasons, a school project, or a variety of other reasons. You should use a wall-marking method to measure your own height. You can use wall-marking, a stadiometer, or even a specially designed horizontal measuring board to measure someone else. Proper posture and head position are critical in all of these situations. Install an app on your phone to measure objects or buildings, and it will do the work for you.

Method 1 Setting Up a Measurement

1. Locate a wall to use as a measuring guide. You’re looking for a wall that allows you unrestricted access. It should be completely solid, with no windows or other cut-outs. It must be large enough to accommodate the person’s shoulders without touching anything else. The area’s floor should also be level.

It’s even better if you can find a wall with a mirror on it. This allows you to keep track of your movements throughout the process, which usually results in a more accurate final figure.

2. Remove all bodily impediments. The individual whose height is being measured should remove their shoes. Place them to the side and remain barefoot (or in socks) for the duration of the measurement. Remove any hair accessories, such as a ponytail, that could obstruct the measuring process. If the person is wearing a bulky coat or jacket, request that they remove it.

One of the reasons for removing bulky clothing is to observe body posture and ensure that the person is standing up perfectly straight when measured.

3. Straighten your back. To measure, move to the wall. Place the person with their back to the wall. Ask them to stand up straight for the duration of the video. When you look at their profile from the side, make sure the backs of their feet, head, shoulders, and bottom lightly touch the wall.

4. Place their legs together. Request that the person bring their legs closer together. Their weight should be distributed evenly between both feet. Their knees and ankles should be close to, if not touching, one another.

This may be an uncomfortable position for some people who have knee problems. Check with the individual to ensure that they are not in any pain.

5. Position their hands and arms to the side of their bodies. Your subject may wish to clasp their hands or cross their arms in front of them; however, this will affect their posture and final height measurement. Instead, instruct them to purposefully hang their arms at their sides.

When measuring a child, you may instruct them to keep their body as straight as a board and their arms as limp as noodles.

6. Instruct them to look ahead. Request that they focus on a spot across the room at eye level height while you complete the measurement. Make a circle around the person, making sure their eyes and ears are horizontal in profile. This is referred to as the “Frankfort Plane” alignment, and it indicates that their head is in the proper position.

To properly observe the Frankfort Plane, you must be at least as tall as the person being measured. So, keep a step-stool nearby in case you need it.

When measuring a child, look to see if they move their head after taking a breath. If this is the case, you should reposition their head before taking a quick measurement.

Method 2 Measuring a Person’s Height Manually

1. Make use of the pencil mark method. Position a pencil horizontally above the person’s head, with the tip facing the wall. Maintaining a level position, lower the pencil until it reaches the top of their head. Move the pencil tip slowly toward the wall until it leaves a mark. Take a flexible tape measure with you. Measure up from the floor to your mark with the tape against the wall.

You can use any marking device, but a pencil is the best because you can erase the marks when you’re done. Simply make a dark enough mark that it is visible when you pull away.

Make sure to keep the tape straight as you work your way up from the wall. It should also be positioned lightly against the wall. If you prefer, you can use a straight ruler to make a wall mark every 12 inches and then add it all up.

You can use this method to measure yourself as well; just keep the pencil level. It also helps if you use a wall opposite a mirror to track your movements.

2. Make use of a stadiometer. This is a piece of medical equipment that consists of a measuring board that is attached to the wall and has a drop-down (adjustable) rod at the top. Allow the individual to stand against the board, and then adjust the rod so that it rests on the top of the individual’s head. You’ll need to write down the height where the rod meets the board if you’re using a manual stadiometer. When using a digital stadiometer, the height is displayed immediately after adjusting the rod.

It is not necessary to press the measuring rod against the individual’s head. It is sufficient to lightly touch the rod to the head.

3. On a horizontal surface, take your measurements. To get an accurate number, have the person lie down on a firm surface. A small child can be examined on an examination table in a doctor’s office. If you’re measuring an immobile adult, use a firm bed. Request that the person look up at the ceiling. Gently press their knees together and down until they come into contact with the flat surface. Measure from the bottom of their feet to the top of their head with a measuring tape.

Keep in mind that this method is less accurate when used on taller people. So, whenever possible, try to use a stand-up wall method.

This is frequently a good option for children who move a lot but are too big for the infant measuring device and too wiggly to stand up to the stadiometer.

You can also measure between the marks made with a pen or marker at the bottom of their feet and the top of their head. If you don’t mind marking up a bedsheet or measuring on a paper surface (as in a pediatrician’s office), this method works well.

4. Make use of a horizontal headboard and footboard device. This is the preferred method for measuring infants. You will place the baby in a measuring area. The headboard and footboard are then pulled toward the baby until they meet at the baby’s head and feet, respectively. To determine height, measure from board to board.

Some of the more advanced measuring devices found in paediatricians’ offices will even display the final measurement or distance between the boards digitally.

5. Make a note of the final measurement. It is always easier to have one person do the measuring while another person writes down the results if at all possible. However, if you are doing everything yourself, make sure to write down the numbers as soon as you get them to ensure accuracy.

Take all of your measurements down to the nearest eighth of an inch (0.1cm).

All measurements should be taken twice if possible. Check to see if the two results are close enough to one another to indicate accuracy. If they are more than 1/8 of an inch apart, you should take another measurement.

Method 3 Measuring an Object’s Height Using Technology

1. Purchase and install a measuring app. Navigate to the app store and look for a “measure app.” A number of options will appear, including the Easy Measure app. Before you buy, read the reviews and compare the prices. Select the one that best meets your requirements and download it.

Easy Measure, for example, has a number of appealing features. It includes an animated tutorial that explains how to deal with measurement problems. It also allows you to photograph the object being measured and save it alongside the measurement for easy reference.

2. Launch the app. When you’re ready to measure something, get within eyeshot of it and pull out your phone. Start the application and complete any calibrations that have been requested. To keep your phone stable, experiment with a few different ways to hold it.

3. Take a look at the object with your camera. Place your camera at eye level and point it at the object of interest. Make sure your fingers are out of the way as well. To get the entire object into the view frame, move forward or backward. This may require some practise, so give yourself plenty of time.

Setting the correct camera height is a part of the calibration process. It is preferable to subtract 4 inches from your height and use that figure (just so long as you keep the camera at eye level).

4. Capture a clear image of the object. Take a few pictures of the object and wait for the measuring magic to happen. The app will display the object’s height and give you the option to save it for later or share it on social media.

If you have any doubts about the accuracy of the final measurement, perform a few test runs on nearby objects. Measure these objects with the camera and then with a traditional tape measure. When you compare the two numbers, they should be 1/8th of an inch apart.
