What are the strongest floor joists?
Since knots and other defects weaken wood, higher grades of lumber (designated as clear, select, or #1) are considered stronger than lower grades. Higher grades of lumber, however, are also much more expensive. Lumber graded as #2 is the most common choice for floor joists and other framing lumber.
What is the difference between I joist and LVL?
The I-joists are made from lumber flanges, OSB webs and cured adhesive. LVL (laminated veneer lumber) beams are manufactured with multiple layers of thin wood assembled with adhesive.
Are 2×6 OK for floor joists?
2x6s may be used for floor joists, ceiling joists, or rafters and have differing spans for the same grades and species. Loads are divided into live or snow loads and dead load considerations. A plank used for a floor joist commonly has different load factors than a ceiling joist or rafter.
How long can a floor joist be without support?
With 16” spacing, a floor joist can span up to 14′ as long as it is not cantilevered and terminates with support on either end. If the joists are 24” apart, then one 2×10 joist can span up to 11′ 5”. These lengths are for SYP lumber.
What kind of wood should I use for floor joists?
The common types of wood used to make floor joists are redwood, hemlock, Douglas fir, and southern yellow pine. However, not every type of wood product is available across the country.

How far can a 2×6 joist span without support?
2-grade 2×6 joists can span up to 10 feet 9 inches from beam to beam when spaced the standard 16 inches apart with a maximum live load of 30 inches per square foot. In comparison, No. -1 grade lumber can span slightly further to 10 feet 11 inches under the same parameters.
What is the proper spacing for floor joists?
Floor joist span is the length of an individual joist, from the foundation walls to an interior beam. The spacing between joists is typically 16”, but can also be 12”, 20”, and 24”. The spacing and ability to span a greater – or smaller – distance is dependent on the size of lumber used for the joists.
Do floor joists have to sit on a beam?
Floor joists spread the loads bearing from above, and must be framed adequately to complete the load paths. Ideally, if a load-bearing wall runs parallel to floor joists, then it should sit directly over a beam or a joist supported by a load-bearing wall below.
Are floor joists always 16 inches apart?
Typically they run anywhere from 12″ to 24″ on center, with 16″ being the norm. This will vary depending upon spans and the type of wood used in the building of the structure.
