How To Take Your Measurements
How to Take Your Measurements
Creating a ZULLO frame begins with you.
These measurements allow us to design a bicycle that fits your body naturally and intuitively. The process is simple and can be done at home in just a few minutes.
You do not need any special equipment—only a measuring tape, a wall, and ideally a second person to assist you.

Before You Begin
- Measure barefoot
- Wear light, fitted clothing
- Use a rigid measuring tape
- Stand naturally—do not stretch or force posture
- Record all measurements in millimetres (mm)
- If possible, have someone assist you for accuracy
The Measurements
Follow the diagram in the form as a visual guide.
A — Height
Stand upright against a wall, barefoot, with your heels touching the wall.
Measure from the ground to the top of your head.
B — Total Body Length
Stand upright and measure from the ground to the sternal notch (the small dip at the base of your neck).
C — Inseam
Stand with your back against a wall.
Place a book firmly between your legs, pressing upward to simulate a saddle.
Measure from the top of the book down to the ground.
This is one of the most important measurements—take it carefully.
D — Upper Leg
Kneel on the ground with your body upright.
Measure from the top of your knee to your crotch, keeping your thigh vertical.
E — Arm Length
Extend your arm straight out to the side.
Measure from the shoulder joint (acromion) to the middle knuckle of your hand.
F — Shoulder Width
Measure the distance between the two shoulder bones (acromion to acromion).
A Final Word
Take your time and measure twice.
Perfection is not required—these measurements are the beginning of a conversation.
Our atelier will interpret them with care, experience, and sensitivity to create a frame that feels entirely your own.
