P = inches1 ¾ X = inches2 ½

R = inches1 15/16

C = inch(es)3/8

K = inches1 1/4

U = inches2 1/8

Z = inches2 3/4 O = inches1 5/8

W = inches2 5/16

H = inch(es)

13/16

F = inch(es)5/8

D = inch(es)1/2

M = inches1 7/16

J = inches 1 1/16

I = inch(es) 1

Y = inches2 5/8

T = inches2 1/16

G = inch(es)3/4

Q = inches1 7/8
