Measure your PD

STEP 1: PREPARE

 

Use your own metric ruler or print our guide above. To print this page, you must download, then print,

to ensure it prints to scale. In your print settings, use the ‘No scale’ or ‘Actual size’ setting.

When printed at the correct scale, the card should be the size of a credit card.

 

STEP 2: FOLD

 

Cut out the PD ruler below and fold it along the dotted line.

 

STEP 3: GET READY

 

Stand in front of a mirror or ask a friend to help.

Place the ruler horizontally against your brow, keeping your face straight.

 

STEP 4: MEASURE

 

Align the zero directly above the center of your right pupil. Without moving the ruler,

follow it over to your left eye and read the measurement directly over the center of your left pupil.

 

STEP 5: CELEBRATE!

 

You did it – you measured your own PD. Now, let’s do some shopping!
