There are any number of ways to anchor your structure to the ground the 2 most common being with posts in concrete that are attached to the floor itself and the other by cable tie downs.
2x4 vs 2x6 for floor joists of storage shed.
3 4 pt plywood floor will not warp and evenly spread the weight as well.
This is very.
Consider going at least 6 x 8 or 8 x 10 if you can.
Using a 2 per foot slope the top of the ridge would be 10 above the top of 2x4 ceiling joists.
Builders will often tout one way or the other as the best way and i will use this space to talk about some of the perceptions myths and facts about.
Wooden shed floors are usually built like the picture below and primarily consist of band boards rim joists floor joists and skids.
If you had a 12 12 shed with a gable roof that would mean 26 rafters which is a lot.
Moving to 16 on center you could span your spf 2x4s up to 6 for heavy loads and 9 for light loads which would still work with a 12 12 gable shed.
For your floor since you re not using a concrete slab you will probably want 16 centers.
Most small sheds use all 2x4s for the floor and band joists.
Two by four construction is by far the most common and is based on the ubiquitous 2x4.
Two by six construction is the main alternative.
So 4 floor 10 roof 3 5 ceiling joists 17 5.
While you may be ok with the joist span at 24 inches the floor will be maxed out to the limits.
By time you frame walls even if you use 2 x 3 studs you re gonna loose 5 of floor space so you ll be down to a 43 width.

A large shed might need larger joists.
Of course the skin is plywood and siding.
I have a shed built completely with 2x4s.
A mr shed is easy for us to move something we often do for our customers.
Wide sheds have 2x4 floor joists 16 o c.
This type of construction has two main types.
The 10 and 12 wide buildings have 2x6 floor joists 16 o c.
All our sheds are mounted to 2 double 2x6 treated skids.
Studs mud sills top plates and rafters.
96 17 5 78 5 6 6 head clearance in the shed.
With a 2x4 band joist and 2x6 floor joists it is problematic.
A gabel roof using 2x4 rafters would have two 5 spans across the 10 width.
I d bump up to 2 x 8 joists if you go the 8 x 10 route.
If you are building an 8 wide and using 2 x4 x92 5 8 precuts then you can use them here without any cutting.
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 the floor joists are 2x6 then the band joists should be 2x6.
You would have to have a monolithic roof for that low slope.
For a shed you re generally okay with 24 centers rather than 16.
Spacing your 2 4 shed rafters at 24 on center limits the width of your roof.
