How to Take Body Measurements Correctly With a Soft Tape

How to Take Body Measurements Correctly With a Soft Tape (August 2026)

by

The scale tells you one number, but your body tells a much bigger story. When I started tracking my fitness journey, I was frustrated that the scale barely moved even though my clothes fit better and I could see changes in the mirror. That is when I learned how to take body measurements correctly with a soft tape, and it changed everything about how I tracked progress.

Body measurements capture what the scale cannot. They reveal fat loss, muscle gain, and shifts in body composition that a single weight number completely misses. Whether your goal is weight loss, muscle building, or simply fitting better in your clothes, circumference measurements give you data you can actually use.

In this guide, I will walk you through the entire process step by step. You will learn which tape measure to use, how to position your body, where exactly to place the tape on each body part, and how to stay consistent so your numbers mean something. I will also cover how to measure yourself without a partner, which is one of the biggest challenges people face at home.

What Type of Tape Measure Should You Use for Body Measurements

You need a soft, flexible tape measure designed to wrap around body curves. The best options are cloth measuring tape, fiberglass tape, or flexible plastic tape made specifically for body measurements. These conform to your skin surface without compressing it, which is exactly what you want for accurate readings.

Never use a metal measuring tape, the kind found in a toolbox or hardware kit. Metal tape is rigid, cannot wrap around curves, and will give you wildly inaccurate numbers. It also pinches the skin and creates gaps between the tape and your body that throw off every single measurement.

Here is a quick breakdown of what works and what does not:

  • Soft cloth tape (sewing tape measure): Ideal, inexpensive, and flexible enough for every body part
  • Fiberglass body tape (MyoTape and similar): Built specifically for body measurements with locking mechanisms for solo use
  • Metal hardware tape: Never use this for body measurements
  • String or ribbon: Too stretchy and inconsistent, leads to unreliable readings

Before you start, check your tape for accuracy. Lay it flat against a ruler and compare the markings at several points. Cloth tapes can stretch over time, especially older ones that have been used for sewing projects. If your tape shows different numbers than the ruler at any point, replace it. A stretched tape means every measurement you take is wrong from the start.

Look for a tape that displays both inches and centimeters. Most quality body tapes include both units on opposite sides, which brings us to understanding how to read them.

Understanding Your Soft Tape Measure: Inches vs Centimeters

Most body measuring tapes print inches on one side and centimeters on the other. To find which side is which, look at the numbers. The side with larger spacing between marks and numbers typically reaching around 60 is inches. The side with tighter spacing and numbers going up to 150 is centimeters.

One inch equals 2.54 centimeters. If your tape only shows one unit, you can convert easily: multiply inches by 2.54 to get centimeters, or divide centimeters by 2.54 to get inches. Most fitness tracking apps and measurement charts accept either unit, so pick one and stick with it for consistency.

The key is never switching units between measurements. If you start tracking in inches, keep using inches every single time. Mixing units creates confusion and makes it harder to spot real progress over weeks and months.

How to Prepare Before Taking Body Measurements

Preparation matters as much as technique. If you measure under different conditions each time, your numbers will bounce around and tell you nothing useful. Here is how to set up for accurate, repeatable results.

Wear minimal clothing. Lightweight underwear or tight-fitting activewear works best. Thick clothes, belts, or layers add bulk and distort readings. Take measurements against bare skin whenever possible.

Stand with proper posture. Stand tall with your feet shoulder-width apart, weight evenly distributed on both feet. Keep your arms relaxed at your sides, not flexed or raised. Look straight ahead, not down at the tape. Slouching or tensing changes your body shape and ruins consistency.

Measure at the same time of day. Your body naturally fluctuates throughout the day due to water retention, food intake, and activity. Morning measurements, before eating or drinking, tend to be the most stable. Whatever time you choose, keep it the same every session.

Breathe normally. Do not suck in your stomach or hold your breath. Take a normal, relaxed breath and measure at the natural resting point. If you hold your breath every time, the measurement is not real.

Use a mirror. Stand in front of a full-length mirror so you can check that the tape sits level and parallel to the floor. A mirror is your best tool for catching uneven tape placement, especially on your back and sides where you cannot see directly.

How to Take Body Measurements Correctly: Step-by-Step Guide

This is the core of the process. I will cover each body part with exact landmark placement and tension guidance. Follow these steps in order, and write down each number as you go.

One universal rule before we start: the tape should lie flat against your skin without compressing it. Think of it as resting on the skin surface, not squeezing into it. If the tape leaves a red mark, it is too tight. If you can slide fingers underneath easily, it is too loose.

1. Chest Measurement

Wrap the tape around the fullest part of your chest, across the nipple line. Keep the tape parallel to the floor all the way around your back. Relax your arms at your sides and breathe normally.

For women, this is typically the bust measurement taken at the fullest point. For men, measure across the widest part of the pecs. Make sure the tape crosses the same spot on both sides of your body and sits flat across your shoulder blades in the back.

2. Waist Measurement

Find your natural waist, which is the narrowest part of your torso. This is usually located just above the belly button and below the rib cage. Bend side to side slightly and the crease that forms is your natural waistline.

Wrap the tape around this point, keeping it parallel to the floor. Do not pull tight. The tape should sit snugly on the skin without sinking in. This measurement is one of the most important for tracking weight loss progress, so consistency here matters more than anywhere else.

Some people also track a separate belly button measurement, taken exactly at the navel. If you do both, record them as separate entries so you do not confuse the two.

3. Hip Measurement

Stand with your feet together. Wrap the tape around the widest part of your hips and buttocks, which is usually about 7 to 9 inches below your natural waist. Make sure the tape crosses the fullest point of your glutes in the back and sits parallel to the floor.

This measurement often shows some of the most dramatic changes during a weight loss journey. Check in the mirror that the tape is level in the back, since it tends to dip down when measuring solo.

4. Arm Measurement

Measure your dominant arm flexed at the midpoint between your shoulder and elbow. Bend your elbow to 90 degrees and flex your bicep. Wrap the tape around the thickest part of the muscle.

For a relaxed measurement, let your arm hang at your side and measure the same midpoint. Pick one method, flexed or relaxed, and use it every time. I recommend flexed for muscle building tracking and relaxed for general body composition tracking.

Record left and right arms separately, since they are rarely identical. Small differences of a quarter inch are completely normal.

5. Thigh Measurement

Stand with your weight evenly on both feet. Wrap the tape around the thickest part of your thigh, just below the gluteal fold where your thigh meets your buttocks. Keep the tape parallel to the floor and do not tense your leg muscles.

If you have trouble finding the thickest part, measure at the midpoint between your hip bone and your knee. Use the same landmark every time and mark it with a small skin-friendly dot if needed.

6. Calf Measurement

Wrap the tape around the thickest part of your calf, which is usually just below the knee. Keep your weight on the opposite leg so the muscle is relaxed. Record left and right separately.

Some fitness trackers also include a neck measurement, taken just below the larynx (Adam’s apple area) with the tape snug but not tight. This is less common for weight loss tracking but useful for clothing fit and certain fitness assessments.

For shoulder width, measure across the back from the outer edge of one shoulder bone to the other. This is easier with a partner but doable solo by reaching behind your back with the tape held across both shoulder points.

How to Measure Yourself Without Help (Solo Measurement Tips)

Most guides assume you have a partner. I know from experience that measuring yourself solo is harder but entirely possible. Here are the techniques I use to get accurate readings without anyone helping.

Use a full-length mirror positioned directly in front of you and a second mirror behind you if available. This lets you check the tape position on your back and sides. If you only have one mirror, turn slowly and use your free hand to feel that the tape sits level.

For back-heavy measurements like the chest and hips, hold the zero end of the tape at the front center of your body with one hand. Use your other hand to feed the tape around your back and bring it to meet the starting point. Pinch the tape at the meeting point, then read the number.

For arms and thighs, you can loop the tape with one hand while holding the zero mark with your thumb. Rotate the tape around the limb until you find the thickest part, then read. This gets easier with practice.

A locking tape measure makes solo measuring significantly easier. Tapes with a retractable button or a pin that locks into a slot let you set the tape, lock it in place, then read the number without holding tension. If you measure alone regularly, invest in one.

Take each measurement twice when doing it solo. If the two readings match, you are confident in the number. If they differ, take a third and use the one that repeats. This simple double-check catches errors that happen when you cannot see what the tape is doing behind you.

When and How Often to Take Body Measurements

Consistency is more important than frequency. Measuring every day will frustrate you because real body composition changes happen over weeks, not hours. Measuring too rarely means you miss momentum and motivation boosts.

Most fitness professionals and experienced trackers recommend measuring every 2 to 4 weeks. This gives your body enough time to show meaningful change while keeping you engaged with your progress. If you are in an aggressive weight loss phase, every 2 weeks works well. For maintenance or slow recomp, every 4 weeks is plenty.

Pick a consistent time of day. Morning measurements before eating or drinking are the most stable because your body has not been affected by food, water, or activity yet. Evening measurements are fine too, but they tend to run slightly larger due to water retention and food volume. Just never mix morning and evening readings in the same tracking log.

Write every number down immediately. Use a notebook, a spreadsheet, or a fitness tracking app. I keep a simple log with the date and each measurement listed in the same order every time. This creates accountability and makes trends easy to spot over months.

Common Mistakes to Avoid When Measuring Your Body

Even with good intentions, small errors compound into unreliable data. Here are the mistakes I see most often, along with how to fix them.

  • Pulling the tape too tight. The tape should rest on the skin, not compress it. If you see skin bulging above or below the tape, loosen it. Compressing the skin can underreport your measurement by half an inch or more.
  • Measuring at the wrong spot each time. An inch higher or lower on your waist or thigh gives a completely different number. Use anatomical landmarks like the belly button, the shoulder-to-elbow midpoint, or the gluteal fold to find the exact same spot every session.
  • Not keeping the tape parallel to the floor. If the tape dips in the back, your reading will be artificially large. Check in the mirror or feel with your fingers to confirm the tape sits level all the way around.
  • Flexing or sucking in. Tensing your muscles or holding your breath produces a number that does not represent your actual body. Relax and breathe normally every time.
  • Measuring at different times of day. Morning and evening readings can differ by an inch or more on certain body parts due to water and food. Always measure at the same time.
  • Using a stretched or damaged tape. Old cloth tapes stretch and give false readings. Check your tape against a ruler periodically and replace it if the numbers do not match.
  • Switching units mid-track. Going from inches to centimeters (or vice versa) makes comparisons harder and invites conversion errors. Pick one unit and commit.

How Body Measurements Reveal Progress Beyond the Scale

The scale is a blunt instrument. It cannot tell the difference between fat, muscle, water, and bone. When you start exercising and improving nutrition, you may gain muscle while losing fat at the same time. The scale stays flat, but your body is changing dramatically.

This is exactly what happened to me. I went six weeks with zero weight change on the scale, but I lost nearly two inches off my waist and an inch and a half off my hips. Without body measurements, I would have given up thinking nothing was working.

Countless people in fitness communities share this exact experience. They report losing inches without any weight change when gaining muscle through strength training. Muscle is denser than fat, meaning a pound of muscle takes up less space than a pound of fat. Your weight might not move while your measurements shrink and your clothes fit looser.

Body measurements also capture recomposition that the scale will never show. Recomposition is the process of simultaneously building muscle and losing fat. It is the goal of many fitness programs, and the only way to track it accurately is with circumference measurements and progress photos alongside your weight.

This is why learning how to take body measurements correctly with a soft tape is one of the most valuable skills for anyone on a fitness or weight loss journey. It gives you real, visible evidence that your efforts are paying off even when the scale refuses to cooperate.

Frequently Asked Questions

How do I measure my body with a soft tape?

Stand with good posture in minimal clothing. Wrap a soft, flexible tape measure around each body part at its specific landmark, keeping the tape parallel to the floor and resting flat on the skin without compressing it. Record each measurement and repeat under the same conditions every 2 to 4 weeks.

Which side of a measuring tape is centimeters?

The side with tighter spacing between marks and numbers going up to about 150 is centimeters. The side with wider spacing and numbers reaching around 60 is inches. One inch equals 2.54 centimeters. Pick one unit and use it consistently for all your measurements.

Is measuring yourself with a measuring tape accurate?

Yes, self-measurement can be accurate if you are consistent. Use a mirror to check tape placement, take each measurement twice to confirm, and use anatomical landmarks to find the same spot every time. A locking tape measure helps with hard-to-reach areas when measuring solo.

How tight should the measuring tape be on my body?

The tape should rest flat against your skin without sinking in. You should be able to breathe normally without the tape feeling restrictive. If it leaves a red mark or causes skin to bulge above and below, it is too tight. If you can slide fingers under it easily, it is too loose.

What is the correct way to take body measurements for weight loss?

Measure your natural waist, hips, chest, arms, and thighs using a soft tape every 2 to 4 weeks at the same time of day. Track the numbers in a log to see trends over time. Focus on the direction of change rather than single readings, since body measurements track fat loss more accurately than the scale alone.

Final Thoughts on Measuring Your Body Correctly

Taking body measurements is simple once you know the process, but the details make all the difference. The right tape, consistent landmarks, proper tension, and steady timing turn raw numbers into a reliable picture of your progress. If you follow the steps in this guide, you will have data that actually reflects what your body is doing.

Start today by grabbing a soft tape measure and recording your baseline numbers. Log them somewhere permanent, then measure again in two weeks under the same conditions. Those first side-by-side numbers will show you exactly why body measurements matter and why learning how to take body measurements correctly with a soft tape is worth the effort.
