Quarter Sawn lumber possess advantages over plain sawn lumber because of the orientation of the growth rings. Because the growth rings in quarter-sawn wood run uniformly parallel along the entire board the wood does not shrink and expand with seasonal variation in moisture as much as flat sawn wood. In addition because of the orientation of the growth rings, quarter-sawn wood is less prone to shrinkage, twisting, cupping and in many cases rot because sap wood is easier to isolate in manufacturing process. Purchasing quarter-sawn wood often requires direct contact and contract with the sawyer.

In acoustic guitars, quarter sawn wood is often used, especially for the sides which must be steam bent to produce compound curves.

• "True" Quarter-Sawn Lumber This link offers another version of quarter-sawn lumber that requires more handling in the sawmilling process but the result is actually true quarter-sawn lumber. Since the purpose of quarter sawing is to produce lumber with the growth rings as close to perpendicular to the sawn faces as possible, the previously described versions, while likely producing good, stable lumber, are not de facto quarter-sawn - as you move out from the centre the result gets closer and closer to Plain-sawn.
