So what is the proper shed floor joist spacing.

This will figure out to be 13.
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.
Joist span and spacing is set by your local building code.
The right spacing depends on the code requirements as well as the type of structure it is and the weight it.
There are three basic measurements used for floor joist spacing.
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.
If you are unsure of what those terms are please have a look a my shed floors page.
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.
This equals 35 00 for just your floor joists.
A shed s sturdiness relates to stud spacing and stud spacing is a notable factor in total materials costs.
There are two stud spacing options for a shed.
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.
The spacing of both joists and bearers will be governed by the type of structural floor decking that is used.
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.
Stud spacing for a shed is important for two reasons.
Studs spaced at 16 inches make for a sturdier shed but the 24 inch spacing is more cost efficient.
There is more than one way to build a shed floor and this is how i build my wooden shed floors.
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.
See table 1 and table 2.
Properly spacing floor joists when framing an addition or whole structure is largely a factor of building codes.
The following instructions refer to different terms like band boards rim joists floor joists and skids.
Lets also assume that you can get a 2x4x10 board at a cost of 3 50.
While you may be ok with the joist span at 24 inches the floor will be maxed out to the limits.
Originally you wanted to frame your shed floor with 16 cc spacing.
16 inch and 24 inch stud spacing.
You would have for a 10 x12 shed 10 floor joists.
There are also several floor joist sizes and types used.
Now lets figure out for building the same 10 x12 floor with 12 cc spacing.
