Introduction
To get a perfect fit, you need the right bust point measurement. The bust point, also called the bust apex, is the highest point of the breast. Knowing how to measure this area correctly helps create better-fitting clothes and supports smart pattern size decisions.
In this guide, we’ll explain how to take bust measurements like apex to apex and shoulder to apex, why these bust adjustments matter, and how to use PLM tools to manage bust data efficiently.
What Is the Bust Point and Why It Matters
The bust point is the fullest part of the bust. It’s a key reference when measuring or drafting patterns for dresses, bras, and bodices.
How Do You Measure the Bust Point?
Use a tape to measure from the shoulder down to the nipple (apex). This distance is your shoulder to apex measurement.
The bust point helps place darts, align cups, and set correct strap positions. Ignoring the bust point can cause tight bust areas or sagging tops.

Apex to Apex |
Horizontal distance from one bust point to the other |
Used in bra and bodice shaping |
|
Shoulder to Apex |
Vertical length from shoulder seam to bust apex |
Aligns neckline, bust shaping, and straps |
|
High Bust Measurement |
Tape around the chest just under the arms |
Needed for accurate bust adjustment |

Full Bust |
Measure around the fullest part of the bust |
Base for bust circumference and cup sizing |

Bust Circumference |
Tape around the bust at nipple level |

How to Measure Apex to Apex
Apex to apex measurement is the horizontal distance between the two bust apex points. This measures how far apart the breasts are and affects how darts and cups are placed.
Step-by-Step Instructions
- Wear a properly fitting bra.
- Stand tall, arms at sides.
- Place the tape across the bust from one apex to the other.
This distance is crucial for bust shaping and symmetry. Patterns must match this value for a natural look.
How to Measure Shoulder to Apex
Shoulder to apex measurement helps determine the vertical position of the bust.
Follow These Steps:
- Stand straight wearing a structured bra.
- Measure from the center of your shoulder seam to the apex.
This measurement ensures bust shaping begins at the correct height. Too short or too long? You’ll need a bust adjustment.
Common Bust Variations and Adjustments
|
Bust Type |
Apex to Apex |
Shoulder to Apex |
Bust Adjustment Needed? |
|
Close-set bust |
15–17 cm |
23–25 cm |
Narrower dart and closer shaping |
|
Standard bust |
18–20 cm |
25–27 cm |
Typical patterns work fine |
|
Wide-set bust |
21–23+ cm |
27–30 cm |
Wider darts and extra shaping needed |
If you feel your top is tight across the chest or gaping at the neckline, you may need a full bust adjustment.
Tips for Accurate Bust Measurements
- Always wear a well-fitting bra during the process.
- Use a soft tape.
- Keep tape level, especially for apex to apex.
- Take high bust and full bust measurements together.
- Measure twice and average if unsure.
Even a difference of just a bit can affect bust area shaping.

When to Remeasure the Bust Point
- After pregnancy or weight change
- When switching bra styles
- When working with different pattern blocks
- Every 6–12 months for active wearers
Bust location can shift over time—remeasuring keeps your fit accurate.
Final Notes
If you want your garments to fit well, the bust point can’t be a guess. Whether you’re working with darts, seams, or cups, accurate bust measurements define the outcome.
So take your time. Grab your tape. Mark the highest point of the bust. Measure from shoulder to apex. Check the apex to apex line. Compare with your high bust. Then let Wave PLM keep track of it all.
Perfect fit starts with the right point. And that point is the bust point.
