Properly spacing floor joists when framing an addition or whole structure is largely a factor of building codes. The spacing of both joists and bearers will be governed by the type of structural floor decking that is used. Spacing joists in your shed 16 inches on center will give you a firmer feel with less bounce and increase the load capacity of the floor. See table 1 and table 2.

Lets also assume that you can get a 2x4x10 board at a cost of 3 50. When building a house or even a deck it is important to confirm you have the correct joist sizes spans and spacing before you get started. This equals 35 00 for just your floor joists. Get the number of floor joists you will need from table 3 and the cut length for the band boards and floor joists and skid spacing from table 2.

There are two stud spacing options for a shed. 16 inch and 24 inch stud spacing. The extra two inches of vertical distance when a floor is framed with 2 x 10 joists rather than 2 x 12s can be quite important for example. So typically i would work on 400mm centres for both types of support using 18 20mm thick decking.

So what is the proper shed floor joist spacing. Common sense tells you that large floor joists can carry more load and spacing joists closer together also increases the load bearing capacity of a floor. Studs spaced at 16 inches make for a sturdier shed but the 24 inch spacing is more cost efficient. The following instructions refer to different terms like band boards rim joists floor joists and skids.

While most residential construction uses 2x8 joists with 16 inch spacing there are many other factors you need to consider when determining the proper joist span length. A shed s sturdiness relates to stud spacing and stud spacing is a notable factor in total materials costs.

This will figure out to be 13. Now lets figure out for building the same 10 x12 floor with 12 cc spacing. The right spacing depends on the code requirements as well as the type of structure it is and the weight it. Cut your band boards and floor joists and lay out the band boards for 16 inches on center and drill two pilot holes for each 2x4joist or three holes for each 2.
