How to Measure Half Chest (Garment Measurement) for tops
The "half chest" measurement is taken directly from the garment itself, not your body. It's a key indicator of how wide a top will be. A top's "half chest" measurement is taken when laid on a flat surface and measured arm pit to arm pit.
What you'll need:
- A top you want to measure (e.g., a t-shirt, shirt, or jumper)
- A measuring tape (cloth or flexible metal)
- A flat surface (e.g., a table or clean floor)
Instructions:
-
Lay the Garment Flat:
- Place the top flat on a clean, hard, and even surface.
- Smooth out any wrinkles or creases, ensuring the front and back layers are perfectly aligned and not bunched up.
-
Locate the Armpit Seams:
- Identify where the sleeve seam meets the main body of the top, directly under the armpit. These are your starting and ending points.
-
Measure Across:
- Take your measuring tape.
- Place one end of the tape precisely at the point where the armpit seam starts on one side of the top.
- Stretch the tape straight across the front of the top, ensuring it remains flat and horizontal.
- Read the measurement at the point where the armpit seam starts on the opposite side.
-
Record the Measurement:
- This figure is your "half chest" measurement.

What's a Half Waist Measurement?
Put simply, a half waist measurement is half the circumference of your waist. Instead of measuring all the way around, you're measuring from one side of the waist to the other when the garment is laid flat.
How to Take a Half Waist Measurement (Step-by-Step)
You'll take this measurement on a garment, not on a person. Here's how you do it:
What you'll need:
- A flat surface (a table or clean floor works a treat)
- A measuring tape (cloth or flexible metal)
Steps:
- Grab your Garment: Lay the garment you want to measure (trousers, skirt, shorts, etc.) flat on your clean, smooth surface.
- Smooth it Out: Make sure there are no wrinkles, puckers, or folds in the waistband. You want it as flat and even as possible, just like it would sit when worn.
- Locate the Waistband: Identify the top edge of the waistband. This is the part that would sit around your natural waist or where the garment is designed to sit on your body.
- Align Your Tape: Place one end of your fabric measuring tape at one side of the waistband, right at the outer edge. Make sure it's snug against the fabric but not stretching it.
- Measure Across: Run the measuring tape straight across the very top edge of the waistband to the opposite outer edge.
- Read the Measurement: Take your reading. That's your half waist measurement!
