How long should dowel pins be?

Twice this length is a common rule of thumb for determining dowel length. For example, if your shortest member is 1” thick and you know your safest drilling depth is 3/4”, then a 1-1/2” dowel should be used. A 1-1/2” length equates to two times the 3/4” thickness. The longer the dowel, the greater the holding strength.
