How Far Can a 2×10 Span Without Support?
An SYP (Southern Yellow Pine) 2×10 lumber span can reach up to 14’ when used as a joist with 16” spacing. If using SPF or Redwood lumber, then the span maximum for the same distances will be half to a full foot less.
How far can 2x10 floor joists span?
2×10 floor joists can span up to 20’. However, this is for 12” o.c. spacing for live loads that are 30 psf. This is unrealistic because any living space or deck requires a joist that can support a 40 psf live load. Otherwise, the joists are not to code.
How far apart should a 2x10 joist be?
The length of one 2×10 joist span depends on the wood species and how far apart it is from the next 2×10. A 2×10 southern yellow pine joist can span 16 feet and 1 inch without support. A doubled 2×10 beam can span 11’ without support for a deck that is 4’ wide. Lengths of 2×10 joists and beams vary depending on the application you are using them ...
What is a 2x10 rafter?
A 2×10 beam, joist, or rafter is merely a part of a larger picture. While we can use span tables and calculators to determine the distance a piece of lumber can bridge before it needs more support, we also need to account for all factors that might affect that piece of wood.
What is the minimum load required for a bedroom?
Bedrooms and attics are the only areas of a house that require less capacity than a 40 psf live load – they only require 30 psf or less. In these instances, you span your 2×10 joists further as they are expected to withstand a lighter load than, say, a deck, living room, or balcony.
How long is a 2x10 joist?
If you have Spruce-pine-fir lumber, then your span changes to 13’ 7” for 16” joist spacing. Redwood can support a 2×10 joist up to 13’ – one entire foot less than Southern yellow pine. As you can see, the species of your wood matter.
How far can a 2x8 span?
In general terms, joists spaced 16 inches on center can span 1.5 times in feet their depth in inches. A 2x8 up to 12 feet; 2x10 to 15 feet and 2x12 to 18 feet. Click to see full answer.
How far can a 2x10 be cantilevered?
Also question is, how far can I cantilever a 2x10? Joist Cantilevers According to the new span tables and IRC provisions, cantilevers can extend up to one-fourth the backspan of the joist. This means that joists, such as southern pine 2x10s at 16 inches on-center, spanning 12 feet are allowed to cantilever up to an additional 3 feet ...
How far can a double ply beam span?
When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on.
What grade of lumber allows the longest span?
Not all trees are created equally strong and the type of tree used to make the lumber affects the spans allowed. Boards cut and graded as "structural select" allow the longest spans. Three other grades, No. 1, No. 2, and No. 3 allow shorter spans.
What is the minimum load required for a house?
Expect the local building code authority to require a dead load rating of at least 10 pounds per square foot, and a minimum live load rating of 30 pounds per square foot. Local codes dictate the minimum load rating allowed based on expected occupancy and other variables, including the area's climate. Areas that receive a lot of snow require a higher live load than an area that receives no snow.
How far can a 2-2x10 span?
Note: If the beam is along the edge of a deck and is loaded with a single span, then 2-2x10’s can span about 15’ without incising and 11’ with incising.
How far apart are beams?
The beams will be 8 feet apart (joist span). They will be resting on posts. The number of posts depends on how far the beams can span. This will be standard pressure treated lumber. I was going to use screws to hold the beams together. Maybe construction adhesive, too.
How many members are needed for a beam?
A beam must be 3 members unless you are getting a PE to do the design for you or you are using southern pine. The beam span also depends what your joist span is between the beams/ledger but lets assume 6' then with southern pine it would be 10' 1".
How much load is on each beam?
You indicate the beams are 8’ on center, so the total load on each beam is: 50 psf x 8’ (4’ on ea.side of beam) = 400 plf
Where are joist span measurements taken?
The illustrations (one for cantilever joists and one for flush rim-beam hung joists) point out where joist span measurements are taken from — the saddle of the ledger mounted joist hanger to the center of a dropped beam or saddle of the hanger on a flush beam.
How much can a deck joist span?
Deck Cantilevers. Section R507.5 notes that deck joists can cantilever up to 1/4 of the joist span. But you’ll notice when you look at the portion of the span table for joists with cantilevers that the joist span for decks with a cantilever is often less than the span for the same sized joist without cantilevers.
How many columns are there in a span table?

Does deck joist span cover load?
Deck Joist Span Calculator — Span tables don’t cover your deck load requirements? The American Wood Council has two handy online calculators that can handle a range of specifics.
Does IRC have a deck joist table?
Until a few years ago, the IRC didn’t have deck joist span tables. But the 2015 IRC included a new one (Table R507.5) that will make it easy for deck builders to spec a joist size for a given span and joist spacing. The table includes spans for common lumber species used for deck framing like southern pine, Douglas fir, hem-fir, redwood, western cedar and other species. The table accounts for wet service conditions and an incised lumber reduction for species commonly incised for pressure treatment penetration.
