What are your thoughs on 5/4 vs 1" deck boards. 16" centres but am concerned the 1" boards could end up being a bit bouncy. Do you think that will be an issue at all? Am using wood, not composites.

True 5/4" boards would be quite expensive. The 1" boards are commonly refered to as 5/4", kinda the same as 1x actually being 3/4".

How long you been doing decking?

why do they call it 5/4? I could see where the confusion comes in:blink:
If he were a professional deck contractor he wouldn't be confused about 5/4 decking which is probably used on 98% of wood decks.

if he were talking about true 5/4 he would likely specify true 5/4. Same as if you were looking for a 2x4. If you wanted true 2x4 you would specifically say that.

Settle down guys.... is True 5/4" and True 1"

Guys,

Some of you may think I am brain dead, but I am not. Really....:party:

The 5/4" I refer to is a true 5/4". And the 1" is a true 1"

If that helps.

I know I can do a sample but not sure if putting a couple boards on is going to give the same result as a full deck.

I understand the wood sizing theory:laughing:. I just wonder why we use the measurements when they are not true to the board sizes anymore
The terminology remains the constant, the dimensions of lumber have been the variable. Besides, who wants to call out for a sheet of 23/32 plywood, which in reality is probably 45/64?:laughing:

The same reason folks still say Centigrade even though it was officially changed to Celsius back in the 50's. But I'm with you. We should be calling 'em 3/2 x 7/2's.

It's the same as calling it 1-1/4" but quicker.

2x is really 1-1/2.

5/4x is really 1

1x is really 3/4


Why do they call it that? because they are those dimensions before being finished at the mill?

edit: Okay, others have already answered this

I do not see the need to spend the money for true 5/4" material. I have not seen any problems with any of the 1" material laid on 16" center framing. That said, I am not familiar with Canada, maybe there is some 1" material that is weaker than what I am used to.

Same reason the store will price it at $7.99 instead of $8.00. It sounds better. 5/4 is usually milled to 1" or 1 1/16". If you were to get 1 1/4" it would need to be milled from 6/4 (1 1/2" rough).

Most finished lumber [sizes] are stated in their rough sizes. So a 4/4 x 8" board is really a 3/4" x 7 1/4", yet they will call it a 1" x 8" all day long. Perception vs reality.
