If you don’t have an idea how to measure the size of a shirt, this post will show you how to do it from start to finish.

Measuring The Size of A Shirt:

Correct measuring of your shirt involves taking measurements of various parts that make up your shirt. We’ll show you how to measure each part right below here.

What you’ll need for this job:

  • Flexible tape measure (it should be at least 36-inch long).
  • A shirt that fits you well. Assuming you’re the wearer of the shirt, make sure you use a short that fits pretty well to ensure you obtain the best possible measurements.
  • A notebook and a pen for recording the measurements.

1. Measuring Chest Size

We start with the chest measurements. Before you can take these measurements, you’ll need to button up your shirt and place it on a flat (hard) surface. Remember to smooth it out to eliminate any wrinkles on top or underneath. Pull it out…but DON’T stretch it.

Grab your measuring tape and place at the top of the seam—where sleeves are attached to the t-shirt body—and measure across to just the same point on the other side of your shirt. Note down the measurements.

2. Measuring Waist Size

With your shirt placed in the same position as above, find its narrowest part (this should lie approx. halfway between the shirt bottom and the armpit; or around the 5th/6th button).

Measure straight across from left to the right and note down the measurements.

3. Measuring Biceps

While the shirt is still buttoned and laid flat on its back, spread out one if its sleeve to the side, smoothen it out such that the sleeve’s bottom seam lies where the sleeve is folded.

Starting from the bottom where the shirt sleeve attaches to the shirt body, take the measurement all the way up to the sleeve’s top folded edge—make sure you keep the tape perpendicular to the folded edge.

Note down the measurements.

4. Measuring Shoulder Width

With your shirt’s back facing up, place your measuring tape at the bottom seam, at a point where the yoke (the fabric sitting across the shoulders) is attached to the sleeve. Spread out your take measure straight across the same spot on the other side of the shirt.

Note down the resulting measurement.

5. Measuring Shirt Length

Placed the buttoned up shirt with the back part facing up. Place your measuring tape at the seam where the collar band and the yoke meet.

Take measurements straight down the middle of the shirt up to the longest point of the shirt hem and note the measurement down.

6. Measuring Sleeve Length

Like in the previous steps (4 and 5), the shirt should remain with the back facing up when measuring the sleeve length.

Extend the right sleeve out and smoothen it out as much as you can. Place your tape measure at the middle of the yoke, right below the collar band, and measure all the way to the seam where the yoke and sleeve attach.

Put your finger at the yoke-sleeve attachment point, hold it in place, and then spread out your tape measure tightly to the end of the shirt cuff on sleeve. Record the resulting measurement to the nearest ¼-inch.

7. Measuring Cuff Circumference

Take one of the shirt’s cuffs and spread it flat with its inside facing up. Spread out the cuff pretty tight to ensure you obtain the correct measurements. Place your tape measure from the center of the button (the stitching will guide you) to the outside edge of the cuff buttonhole.

Note down the circumference to the nearest ¼-inch.

8. Measuring Shirt Seat Size

With the shirt lying on a flat surface and facing up, measure the seat size from the left side bottom hem straight across to the right side bottom hem.

9. Measuring Collar size

The final step involves measuring the collar size. To do this correctly, you'll first need to unbutton the shirt and lay it on a flat surface. Open the collars and spread it out as flat as possible. Like in the case of cuff, pull the color tight to ensure you don’t leave any curves that can lead to misleading measurements.

Measure the collar size from the center of the button all the way to the middle of the opposite buttonhole.

Again, record the resulting measurement to the nearest ¼-inch.

Tips and Tricks To Keep in Mind:

  • All the measurements should be taken with the shirt fully buttoned and laid on a flat surface. Hanging the shirt can easily stretch it when making measurements, resulting in skewed measurements.
  • Measure twice. If you don’t get the same measurements in the two instances, try again!
  • Always record your measurements to the nearest ¼-inch.
  • Taking photos of different sizes can help you save time and energy as you don’t have to spend time recording on a paper with a pen.
  • Never take cloth measurements with the ruler. Always use the flexible tailor’s tape measure for accurate results.
  • Above all, keep in mind that different manufacturers do not make their clothes with similar specifications. In other words, you should always check the size specifications before buying (especially when ordering online).

The correct shirt measuring involves measuring the various sections of a shirt—which include the cuff circumference, collar, shoulder width, chest, waist, shirt length sleeve length, seat measurements, and the biceps.

For the most accurate measurements, be sure to record ALL your shirt measurements to the nearest ¼ of an inch. And ONLY stick to the tailor’s flexible tape measure and not the ruler or any other measuring tool.
