Due to the simplicity of preparation, rough sawn timber is always cheaper than planed. As a result, it is the best choice for jobs where the finish of the wood is not important, or when you intend to machine, plan or finish the wood yourself. Our guide below will help you choose the best sawn timber board size to achieve the results.

What you buy			What you can do with it
Nominal board size - Board thicknesses (mm)			Projected finished size (if you intend to plane it)
These are the sawn board sizes you will receive. Please note this can vary by a couple of millimetres from species to species.	18		13mm	This is the projected, maximum size you will acheive once planed
	25		20mm
	32		26mm
	38		32mm
	50		44mm
	65		56mm
	75		70mm
	100		90mm
Width Guides
It is recommended that you allow at least 10-15mm wider than you need to acheive (as a finished/planed board) - SEE EXAMPLES:
Sawn board to select	130		115	Intended finish after your machining
	185		170

* please note that the above information is to be used strictly for guidance. Board sizes can vary and machining methods and tools will influence the finished sizes. You may also be intending to use the boards in the sawn form therefore; the above is not relevant. For more info please get in touch with us.

For Planed Timber the sizes you enter are the finished sizes you will receive. Planed boards are produced from nominal thickness sawn boards. Our guide below will help you choose the best timber board size to achieve the best planed timber results.

Comment	Range		Produced from - nominal board size
The sizes you enter are the finished sizes you will receive. Planed boards are produced from nominal thickness, sawn boards. For best value consider this table	8-14mm		18	Not available in some species it is then produced from next available board thickness
	15-20mm		25
	21-26mm		32	Not available in some species it is then produced from next available board thickness
	27-32mm		38
	33-44mm		50
	45-56mm		65
	57-70mm		75
	71-90mm		100	Not available in some species it is then produced from next available board thickness
It is recommended that you re-consider certain thicknesses if on the borders of the suggested ranges above SEE EXAMPLES:
Your chosen board sizes (mm)	21-22		20	Consider these alternatives (mm) and make considerable savings (upto 30% less waste)
	33-34		32
	45-46		44
