Description

The lengths and sizes of joists vary depending on the species and quality of the lumber used.  For example, you can span a #1 grade (no knots) southern yellow pine a greater distance than a #2 grade (with knots) southern yellow pine.

The #1 grade material is more expensive than the #2 grade, but if you can use fewer or smaller #1 grade joists or rafters in your design, you may actually save money.

Rafter spans can be extended slightly beyond what the rafter tables suggest, when there is a cantelever extending beyond the supporting wall.
