Glass thickness for home-made tanks

A number of people have been asking about glass thickness for home-made tanks and several people suggested a graph which appeared in the book "The Living Aquarium", which is now out of print. This may not be legal, but here it is anyway (so sue me).

from "The Living Aquarium", Peter Hunnam (AB Nordbok 1981)

Glass Thickness as a function of length and depth (Metric Scale)
Length in cm -->
Depth 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190
90 d d d e e e e e e f f f f f f f f f f

d 10 mm (2/5") 12 mm (1/2")
e 12 mm (1/2") 15 mm (3/5")
f 15 mm (3/5") 20 mm (4/5")

Note: The original illustration featured a graph, not a table. I am just providing "eyeball guesstimates" of where the curves fell on the original graph. When in doubt about which thickness glass to use, err on the heavier side (choose the next thicker glass thickness.)
