In your socks or bare feet, stand with your heels and buttocks against the wall and your feet 8” apart. Stand up straight and measure from the ground to the top of your head.
In your socks or bare feet, stand with your heels and buttocks against the wall and your feet 8” apart. Find the notch at the top of your ribcage/ bottom of your neck. Measure from the ground to the bottom of the sternum
In socks or bare feet, stand with your feet 8” apart. Take a level approximately 2ft long and put it between your legs. Pull the level up with the same pressure you feel when sitting on a saddle, approximately 25lbs, and have your helper level the level and measure from the ground to the top. A second option is to stand against a wall and place a large book with a 1" binding between your legs and firmly against the wall so that the book is at a right angle. Pull the book up against your pelvic bone with saddle pressure, approximately 25lbs, and measure from the top edge of the book to the floor.
Stand with both arms out to the side parallel to the ground and measure from your armpit touching your ribs firmly to the web between your thumb and index finger. (Approx. the center of your palm) Please note: Do NOT measure to the tip of your fingers.
Measure your shoulder width by the outside of the bony protrusions at the top of your shoulders. You want to have the tape measure running in a straight line and not wrapping around your back.
In your socks or bare feet, stand with your feet 8" apart and your knees locked. Bend over and see how far you can stretch based on the chart below. Please note: to take this measurement properly you want to be warmed up like you would be when riding your bike.

Set your feet approximately 8" apart and straddle a straight edge - something like a square or a 2' level is ideal. Put as much pressure on your crotch as you feel when sitting on your bike seat. Measure the distance from the top of the level to the ground.
Sit on a stool with your back straight and your pelvis hard against the wall. Make sure your back is straight and your pelvis is against the wall. Place the level on top of your AC (Acromioclavicular) joint and against the wall. The AC is the bony bump on top of your shoulder. Measure from the bottom of the level to the top of the stool. Measure both sides of your body and average the measurements.
Hold a cylindrical object (a magic marker is ideal) in your fist. Lower your arm so that it is to your side, and extend your forearm in ahead of you. Keep the object in your hand perpendicular to your forearm, and measure from the center of the object, which should fall in line with your knuckles, to the boney protrusion at your elbow pivot.
Continue to hold the cylindrical object and extend your arm in front of you, holding your arm parallel to the ground. Try not to allow your shoulder to come forward. Make sure that the object in your hand is perpendicular to your arm. Locate the Pivot of the arm to shoulder point and measure from this point to the center of the object, which should fall in line with your knuckles. Measure both arms and average the measurements.
Sit on a stool again making sure your back is straight and your pelvis is hard against the wall. Make sure your femur is parallel to the ground and your tibia is perpendicular to the ground. Place the level across the front of both of your kneecaps, then measure from the inside face of the straight edge to the wall. Take this measurement from both legs, then take the average.
Remain seated. Place the level across the top edge of your kneecaps (where they connect to the bottom of your inner quadriceps muscles). Measure from the bottom of the level to the ground.
Stand up against the wall. Set your feet approximately 8" apart. Find the sternal notch in your neck - it's the bony "V" immediately beneath your Adam's apple. Measure the distance from the apex of the notch to the floor.
