Depends on the size design and load of the deck but use treated sawn timber at least 2 x 6 c16 grade.
The big sheds generally stock what you will need but select the timber yourself and examine for twists, splitting cupping etc. If you order online say from Wickes you are at the mercy of whoever does the picking. It’s even worth hiring a van to carry the long pieces if you’re carrying out a big project to ensure control over selection of timber

Joists and ledgers should ideally be the same cross section. Solid strutting (noggins are in walls) needs to be at least 2/3 the depth of the joists and the same width

Depending on whether any of the timber is going to be in ground contact, I've previously gone for HC4 treated wood, such as this here:

It's potentially overkill, but given that I only want to be doing the thing once, I went for it!

I used 4x4 every 1.5m, to 70cm depth (Decking raised by about 60cm at the lowest ground level point)
Then 6x2 for ledgers and joists, at 50cm centres. Noggins were made from offcuts of joists. All C24 grade timber. M10 coach bolts hold the whole construction together, with some joist hangers for the intermediate joists. No bounce at all!
Maybe just a Jersey issue, but B&Q (The only shed) has a terrible selection of timber and its expensive. Got a builders merchant to supply it all, which also meant getting 5.4m lengths which saved joins....

I.e every 1.5M across is a new joist, and joists going the other way (horizontal) at 70?
No. Every 1,5m in a grid is a 4x4 timber into the ground.
Then there is an outer frame on all 4 sides of 6x2, bolted to these 4x4s.
From front to back are joists spaced 50cm apart.
Where these meet a 4x4 after 1.5m, there is another 6x2 going left to right underneath the joists.
I'll find a photo....

Interesting... And thanks for the pics.
What does the team think about the view (mainly from the US I think) that face fixing to 4x4 posts is the work of the devil and the posts should be notched to house the joists? I think I see the point but I am not sure...

Sorry if i'm being stupid here, but this is a basic concept, the grey squares are potentially raised blocks which the joists will sit on (this looks way to many), but they are spaced at 1.5 meters away from the house, and 400mm across the house, and the decking boards will span horizontally across. Is this right or wrong?
The green is the grass edge, the brown boards are the 6M long joists.

I've not got much ground clearance between the ground and the underside of my door sills so im possibly limited, the ground is block paving and im going to be putting 1 or 2 bricks underneath the joist depending on the height as my ground is 2 different levels
Any other feedback of the number of support posts? They are the grey ones and i've got about 100 based on that drawing, so in theory that is 100 solid brick/concrete support areas with posts connected to? Have i miss calced or worked it out incorrectly? This is based on one every 1.5M away from the house, and then 400mm centres across the house, with the decking also running across the house.
