Our measurements should be DIAMETER X DEPTH. Remove rims and heads, and measure from top edge of raw shell to bottom edge of raw shell for DEPTH and then measure the outside edge of the shell across the drum for DIAMETER.
We always cut wraps back 1/4 inch on each side to prevent interference with bearing edges. We also recommend cut back of 1/8 inch on most wood bass hoop inlays. Metal hoop inlay sizes are usually exact.
