Girth

Girth is more significant than length.

The incredible girth of a Sequoia tree is necessary to support its titanic height.

Due to his expanding girth, he shifted from belts to suspenders.

He was standing on the offside of his horse, holding up the flap of his saddle, with the surcingle loosened, and was pointing to the girths. Close to their attachment to the saddle they had been almost cut through with a knife.

He's a lusty, jolly fellow, that lives well, at least three yards in the girth.
