Step 4 of 13

Find the following points on your body

You may consider placing a sticker or a piece of tape on them.

1. Top of the Shoulder (Acromion) — the bony point at the top/outer edge of the shoulder.
   How do I find this?

   • Let your arm hang relaxed at your side.
   • Place your fingers on the top of your shoulder.
   • Slide your fingers outward, away from your neck, until you feel a hard, flat bone.
   • Stop where the shoulder starts to slope down toward your arm.
   • Mark the outermost point of that bone.
2. Front Hip Bone (ASIS) — the front-most point on the pelvic bone.
   How do I find this?

   • Put your hands on your hips.
   • Slide your fingers forward along the top of your hip bones.
   • You'll feel a firm, pointed bone at the front of each hip, a few inches to the side of your belly button.
   • Mark the tip of that bone.
3. Inside of the Knee (Medial Femoral Epicondyle) — the bony bump on the inside of the knee when sitting.
   How do I find this?

   • Sit with your knee bent about 90° and your foot flat on the floor.
   • Feel the inside of your knee.
   • Move your fingers just above the knee joint until you find a large, rounded bump of bone.
   • Mark the center of that bump.

Measurement 1 of 8

Height

1. Stand barefoot with your back against a flat wall.
2. Keep your heels on the floor, legs straight, shoulders relaxed, look straight ahead.
3. Place a hardcover book flat on top of your head, one edge touching the wall.
4. Mark the bottom edge of the book on the wall.
5. Step away and measure from the floor to the mark.

Measure twice and use the average.

Measurement 2 of 8

Shoulder Height

1. Stand barefoot on a hard, level floor, upright, shoulders relaxed.
2. Locate the acromion.
3. Place a rigid book or ruler horizontally at the acromion, extend it to a wall.
4. Check level, mark the wall at the book's lower edge.
5. Measure vertically from floor to mark.

Measure both shoulders and record the average, especially if one sits higher.

Measurement 3 of 8

Shoulder Breadth (acromion to acromion)

1. Stand naturally, shoulders relaxed.
2. Find the acromion on each shoulder.
3. Measure in a straight line from the center of one acromion to the other.

Measurement 4 of 8

ASIS to Floor

1. Stand barefoot, weight evenly distributed.
2. Locate the ASIS.
3. Mark its center.
4. Hold a book/ruler horizontally from the mark to a wall, level.
5. Mark the wall.
6. Measure vertically from floor to mark.

Measure left and right separately, then enter the average of the two below.

Measurement 5 of 8

ASIS Distance

1. Stand upright, feet parallel, weight even.
2. Find the left and right ASIS.
3. Mark each.
4. Measure the straight-line distance between marks (keep tape horizontal).

Alternative if you don't have a flat stomach: face a wall, have someone transfer each ASIS position onto the wall with a rigid square, then measure between the wall marks.

Measurement 6 of 8

Knee Joint Height

1. Stand barefoot facing a wall, legs straight and relaxed.
2. Find the bony bump on the inside of your knee.
3. Hold a book level with the bump, mark the wall.

Measure both knees, then enter the average of the two below.

Measurement 7 of 8

Arm Length

1. Extend your arm straight, elbow fully extended.
2. Keep shoulder relaxed, don't reach it forward.
3. Measure from the acromion to the center of the wrist crease.

Measure both arms, then enter the average of the two below.

Measurement 8 of 8

Foot Length

1. Place paper on the floor against a wall.
2. Stand barefoot on it, heel touching the wall.
3. Mark the end of your longest toe.
