Taking accurate body measurements is the step that most beginners rush — and inaccurate measurements lead directly to poorly fitting garments regardless of how carefully the pattern is sewn. This complete guide ensures you take every measurement correctly. Read our guide on how to use a sewing pattern alongside this article for complete pattern preparation.
Why This Pattern Is Perfect for Beginners
- Accurate measurements take 10 minutes and prevent hours of fitting frustration
- Measurements should be taken regularly — bodies change and so do measurements
- Different garments require different measurements — know which ones matter for each type
- Wearing minimal clothing when measuring ensures accuracy
- Two people producing the measurement gives much more reliable results than measuring alone

Garment Measurements You Need
Tops/dresses: bust, underbust, waist, hips, shoulder width, sleeve length, back length
Bottoms: waist, hips, inseam, rise, thigh
Tools Required
A flexible fabric measuring tape (not a rigid ruler), a mirror or measuring partner, and a pen and paper to record measurements. Optional: a measurement chart printed from online.
What to Wear
Wear minimal clothing — fitted underwear or a thin base layer. Measurements taken over thick clothing are significantly inaccurate.
When to Remeasure
Remeasure every 6-12 months, or any time your body changes significantly. Always remeasure before starting a new project rather than relying on measurements from months ago.

Step-by-Step Sewing Guide
Bust measurement
Measure around the fullest part of your bust, with the tape horizontal all the way around. Keep the tape snug but not tight — you should be able to slide two fingers under it. Measure while wearing a well-fitting bra.
Waist measurement
Measure around your natural waist — the narrowest point between your ribs and hips, typically about 2.5cm above your belly button. Breathe normally and measure at the end of a normal exhale.
Hip measurement
Measure around the fullest part of your hips, typically 20–23cm below your natural waist. Stand with feet together and keep the tape horizontal all the way around.
Inseam measurement
Measure from your crotch to the floor, standing straight in bare feet or in the shoes you plan to wear with the finished garment. This is easier to do with a partner.
Rise measurement
Measure from the crotch (where the legs join) up to your natural waist. This measurement is used for trouser and shorts patterns to ensure the crotch depth is correct.
How to use measurements with a pattern
Compare your measurements to the pattern size chart. For tops, size by bust. For bottoms, size by hips. If you fall between sizes, choose the larger size and take in rather than struggle with a too-tight garment.
Frequently Asked Questions
Which body measurement matters most for sewing patterns?
For tops and dresses, your bust measurement is most important. For skirts, pants, and shorts, your hip measurement is most important. The waist is usually adjusted by the elastic or waistband rather than requiring the most precise size matching.
How tight should I hold the measuring tape?
Snug but not tight — you should be able to slide two fingers under the tape easily. Too tight gives underestimates that lead to garments that are too small; too loose gives overestimates that lead to too-large garments.
Do I need to measure myself for every pattern?
Not necessarily if you are using the same size consistently. However, remeasure if your body has changed, if you are trying a new pattern brand (size charts vary), or after any significant gap in sewing.
