How to Measure for Pattern Adjustments
How to Measure for Pattern Adjustments
The secret to well-fitting garments isn't complicated patterns or expensive fabric - it's accurate measurements. Taking measurements correctly is a skill that will serve you for your entire sewing journey.
Essential Tools
Before you start, gather:
- Flexible measuring tape (not a metal carpenter's tape)
- A mirror (or a friend to help)
- Fitted clothing (not bulky sweaters)
- A notepad to record your numbers
Take measurements over well-fitting undergarments that you'll wear with the finished garment. A different bra can change your bust measurement significantly!
The Key Measurements
High Bust
Why it matters: This measurement determines your pattern size and is crucial for bust adjustments.
How to measure:
- Stand naturally with arms slightly away from body
- Wrap the tape under your arms
- Position tape above the bust fullness
- Keep tape parallel to the floor
- Breathe normally and note the measurement
Full Bust
Why it matters: Combined with high bust, this determines if you need an FBA or SBA.
How to measure:
- Wrap tape around the fullest part of your bust
- Keep tape parallel to the floor
- Don't pull tape too tight - it should just touch skin
- Note where tape sits on your back (mid-shoulder blade area)
Bust Apex Location
Why it matters: The apex is your pivot point for bust adjustments.
How to measure:
- Measure from center front (between collarbones) to your bust point
- Measure from shoulder seam to bust point
- Record both measurements
Waist
Why it matters: Essential for bodice length and waist shaping.
How to measure:
- Find your natural waist (bend side to side - it's the crease)
- Tie a string or elastic around your natural waist
- Measure around, keeping tape level
Hip (Full Hip)
Why it matters: Needed for skirts, pants, and fitted dresses.
How to measure:
- Stand with feet together
- Measure around the fullest part of your hips/seat
- Usually 7-9 inches below natural waist
High Hip
Why it matters: Some patterns use this for fitting through the tummy area.
How to measure:
- Measure 3-4 inches below natural waist
- This is around the upper hip bones
Advanced Measurements
Front Waist Length
From shoulder seam (at neck) down over the bust to the waist.
Back Waist Length
From prominent bone at back of neck (C7) down to natural waist.
Shoulder Width
From shoulder tip to shoulder tip, across the back.
Arm Length
From shoulder tip to wrist bone, with arm slightly bent.

Common Mistakes to Avoid
Mistake 1: Measuring Too Tight
The tape should touch your body without compressing. Think of it like measuring a gift box - you want it snug but not squished.
Mistake 2: Inconsistent Posture
Stand the same way each time you measure. Natural posture, not military straight or slouched.
Mistake 3: Measuring Alone When You Shouldn't
For back measurements especially, a helper ensures accuracy.
Mistake 4: Not Recording Measurements
Write them down immediately! Memory is unreliable, and measurements change over time.
Re-measure periodically. Bodies change, and measurements taken a year ago may not be accurate today.
Using Your Measurements
Once you have accurate measurements:
- Compare to pattern size charts - Use high bust for tops, hip for bottoms
- Calculate bust differential - Full bust minus high bust
- Note any length adjustments needed - Compare front/back waist length to pattern
- Enter them in Bombajom Patterns - We'll calculate the adjustments automatically
