Best Body Tape Measures for Waist & Body Fat

Every calculator on this site starts with a tape measure. Here's what to use, from the type the Army uses to tapes that lock around you or log readings to your phone.

Quick Picks

What to Look For

  • No stretch. Cloth tapes stretch with use and slowly throw off your numbers. Fiberglass or coated tapes hold their length.
  • A way to control tightness. A locking loop, push-button retraction or spring tension helps you pull the tape to the same snugness every time.
  • Both units. Inches and centimeters on the same tape make it easy to use any calculator.
  • Enough length. 60 inches (150 cm) covers most waists; choose a longer tape if you need it.

Our Picks

Closest to the Army method

1. Retractable Fiberglass Tape Measure

The Army's measurement guidance asks for a non-stretch tape, preferably retractable fiberglass, and rules out cloth and steel. If you're practicing for an official measurement, this is the kind of tape your unit will use.

Why we like it
  • Doesn’t stretch with use, so readings stay consistent over months
  • Cheap and widely available in 60-inch lengths
  • Matches the tape type in the Army procedure
Keep in mind
  • No tension control: you have to judge “snug” yourself
  • Easiest with a second person holding the tape level

Best for measuring yourself

2. MyoTape Body Tape Measure

The tape loops around your waist and locks into its own housing, then a push button lets it retract to a snug fit. That makes it one of the easiest ways to get a level, repeatable waist reading on your own, and the Navy's body composition guide names the MyoTape as an example of its preferred tape.

Why we like it
  • Locks around you, so both hands are free to keep it level
  • Push-button retraction gives a similar snug fit each time
  • Inches and centimeters, up to 60 inches
Keep in mind
  • Reading starts about 1¾ inches in because of the housing, which takes getting used to
  • The Army prefers a plain retractable fiberglass tape for official measurements

Most consistent tension

3. Gulick Anthropometric Tape (Baseline)

A Gulick tape has a small spring attachment that applies the same force every time you pull it to the mark. It's the style used in many clinics and research studies to take the guesswork out of “snug, not tight.”

Why we like it
  • Spring tension makes repeat measurements more consistent
  • Calibrated in inches and centimeters
  • A favorite of trainers and clinicians who measure many people
Keep in mind
  • Woven fabric tape rather than fiberglass
  • Pricier than a basic tape, and easiest to use with a partner

Clinical grade

4. seca 201 Circumference Measuring Tape

seca is a long-standing maker of medical scales and measuring equipment. The 201 is a retractable circumference tape built for clinical use, with a housing that sits comfortably in the hand.

Why we like it
  • Retractable, locks in place precisely
  • Long range (up to 80 inches / 205 cm) for larger waists
  • Durable housing designed for daily clinical use
Keep in mind
  • Costs more than consumer tapes
  • More than most people need for occasional home checks

Best for tracking progress

5. RENPHO Smart Tape Measure

A Bluetooth tape that sends each reading to the RENPHO app, so you can track your waist (and other measurements) over time without writing anything down.

Why we like it
  • Logs readings to an app with trend graphs
  • Retractable and locking, 60 inches
  • Handy if you already use a RENPHO scale
Keep in mind
  • Needs a phone and an app account
  • Bulkier than a simple tape, with a battery to keep charged

Getting a Reading You Can Trust

The tape matters less than how you use it. Measure at the navel, keep the tape level all the way around, and read it at the end of a normal breath out. Take three readings and average them. Full step-by-step guide →

Frequently Asked Questions

What kind of tape measure does the Army use for waist-to-height ratio?

The Army's measurement guidance calls for a tape made of non-stretchable material, preferably a retractable fiberglass tape. Cloth tapes are not allowed because they stretch with use, and steel tapes are not allowed because they don't conform to the body.

Can I use a sewing tape measure for my waist?

You can, but cloth sewing tapes stretch over time, so your readings slowly drift. A fiberglass or locking body tape gives more consistent results, which matters when you are tracking small changes.

How tight should the tape be?

Snug against the skin without pressing in. Measure at the end of a normal breath out, without sucking in your stomach. Tension-controlled tapes like a Gulick or MyoTape help you apply the same tightness each time.

How often should I measure my waist?

Once a week, at the same time of day, is plenty for tracking progress. Daily measurements mostly pick up normal swings from meals and water.
