The clothing measurements around your biceps can determine the comfort of your clothing. It also determines how the piece of clothing looks when you wear it. Measuring biceps is of utmost importance if you want a t-shirt or shirt to fit you well and give your arms room to move. In this article, we’ll provide you with the steps to measure your biceps accurately and give you tips to make the process easier.

Why Measuring Biceps is Important for Clothes Sizing

Before we jump into the steps for measuring biceps, let’s understand its importance. Biceps are your upper arm muscles. And the circumference around your upper arm can make or break your outfit.

For example, if your tops, t-shirts, or dresses have very small openings for your arms, you’ll feel tightness, discomfort, or even a lack of mobility. On the other hand, if the arm openings are really large, you’ll end up with baggy, ill-fitting clothes.

Without further ado, let’s get into the steps to measure biceps accurately for your clothing or for fitness checkups.

Steps to Measure Biceps Accurately

Before you begin, find a flexible tape measure. You can use a tailor’s tape measure, which is ideal for body measurements. If you don’t have one, use a string or a ribbon and measure it with a ruler afterward.

Step 1: Relax your arm and keep it straight by your side

Make sure your biceps are not flexed or tensed. We need the measurement of your natural arm circumference.

Step 2: Wrap the tape measure

Wrap the measuring tape about three to four inches below the armpit. This is generally the widest part of your bicep. Ensure that you do not wrap it too tightly as we want some room for movement.

Step 3: Note down the measurement

Write down the measurement in inches or centimeters, depending on your preference. Add a quarter-inch or half-centimeter to the measurement for some flexibility

Step 4: Repeat for the other arm

Since both biceps can have slightly different measurements, make sure you measure both arms to get the accurate sizes. Use the larger measurement to find clothing online or provide both measurements to your tailor if you’re custom-making clothes.

Tips for Accurate Bicep Measurement

While the above steps are straightforward, there are some tips to ensure accurate bicep measurement:

  • Measure your biceps bare skin for the most accurate measurements. Measuring over full-length shirts can add bulk to the measurement giving you inaccurate results.
  • Biceps can get larger or smaller depending on your activities throughout the day. Take the measurements for both arms at the same time.
  • If you work out, measure the biceps once after the workout as well. Pumped-up biceps will be slightly larger and can cause discomfort if you buy clothes with smaller bicep measurements.

FAQs

What should I do if my biceps measurement falls between two sizes?

If your biceps measurement falls between two sizes on the size chart, we recommend going with the larger size. You can always tailor the garment later for a more personalized fit.

Can I measure my biceps with a non-flexible tape measure?

While you can use a non-flexible tape measure, it might not give you an accurate measurement, as it won’t conform to the curve of your arm.

How often should I measure my biceps for clothes sizing?

We recommend measuring your biceps at least once a year, as your body shape might change due to weight loss, gain, or muscle growth.
