I want to make a fence with 3 different sized planks. You know when wood is measured say 2xa4 or 2×8 etc and how long are they? Thanks so much.
Also is pressure treated wood available in planks?
I want to make a raised vegetable bed with them too.
I live in Ireland so would have to be measurements recognised here. Thanks
Yes, pressure treated lumber is available in ‘planks’. Here in the USA, the most common use for them would be outdoor decks/stairs.
As to the lengths, its fairly common to find them about 6ft, 8ft, and 10 ft lengths, but they can also be bought in 12 ft, and longer lengths. The longer the length, the more it will cost. (6ft = 182.8 cm, 8ft = 2438.4mm)
The ‘2×4′ designation refers to the original cut dimension of the lumber. It is then planed smooth, and kiln dried, (which shrinks it a bit), so a ‘2×4′ ends up closer to 1.5" x 3.5" ( 38mm x 89mm)
Common lumber sizes here in the USA are:
"1×3" = 19mm x 63.5mm
"1×4" = 19mm x 88.9mm
"1×6" = 19mm x 139.7mm
"2×4" = 38mm x 89mm
"2×6" = 38mm x 139.7mm and so on…. It may be more common for suppliers in your area to round up the numbers, so – 88.9 would be 89mm, and 139.7 might be more often referred to as 140mm
Here is a conversion chart, should you need it – http://www.worldwidemetric.com/metcal.htm
Just remember that the ‘actual’ dimension of width and depth is usually a half inch less than the nominal dimensions. Length, however, is dead on. A 2×4x8 stud is actually 1.5" x 3.5" x 8ft (38mm x 90mm x 2438.4mm)
Check with your local lumber suppliers to see what is available in your area.
Have Fun
