End Grain, Edge Grain, or Face Grain? The Best Wood Uses for Projects

When starting a wood project, it is important to understand the differences in wood cuts, as well as why moisture measurement and moisture control matter. When it comes to wood grain, any piece of lumber has three surfaces: end grain, edge grain, and face grain.

What Is End Grain?

End grain is the surface you see when wood is cut across the grain, at a 90-degree angle to the length of the wood fibers. Rather than running along the length of the trunk, the cut exposes the ends of the fibers and shows the growth rings.

Many woodworkers like the look of end grain, with its rings, color, and character, and it is also very durable.

End grain is typically used to make butcher blocks, for example. The boards are made by cutting lumber into blocks and gluing the blocks together with the end grain up, forming the top surface of the cutting board.

This block construction makes the butcher block very strong and durable. During cutting and chopping, the knife edge slips between the end grain fibers instead of slicing across them, so the block resists nicks and gouges. Think about how much chopping a butcher block takes over the years, and you can see why end grain is used.

End grain flooring is a less common form of wood flooring that has been used for one main goal: durability. End grain floors were traditional floor coverings in factory buildings, heavy traffic commercial buildings, and boardwalks, to name a few applications. They absorb energy and noise, and the orientation of the fibers helps them resist scraping and general wear.

Wood holds moisture as bound water in its cell walls and as free water in its cell cavities, and it can give up or take on moisture readily depending on the relative humidity (RH) of the surrounding air. According to the USDA Wood Handbook, wood absorbs water most rapidly through the end grain.

If you consider that most wood cells have a roughly drinking straw-shaped structure, you can see that the moisture can travel more quickly into and out of the wood from an end-grain cut.

Many wood professionals recommend sealing end grain to slow down moisture exchange, even before beginning a project. When storing wood for extended periods of time or in areas without climate control, sealing the end grain is also highly recommended, especially to prevent end splits.

Edge Grain & Face Grain

To carry on with our butcher block example, there are two alternatives to end grain when making a butcher block.

Edge grain (or vertical grain) lumber is produced by quartersawing, so that the edges of the growth rings are exposed on the widest faces of the piece and the rings form angles of 45 to 90 degrees with those faces.

What Is Face Grain?

Face grain is the wider side of a board, as opposed to the narrower edge. The term may also refer to the face that will be visible in the finished product.

Edge grain butcher blocks are usually made of strips of wood, and after the lumber has been cut into strips, there is a choice of which grain to put facing upwards. When the edge grain is up it is an edge grain cutting board, and when the face grain is up it is a face grain cutting board.

The key difference from end grain is that these surfaces are a little more resistant to stains and absorbing moisture.

You may also hear woodworkers use the term flat grain. Flat grain (or flatsawn) lumber has growth rings that meet the wide face at an angle of less than 45 degrees, which produces the familiar cathedral pattern on the face. When a board or a glued-up panel includes both flat grain and edge grain, it is called mixed grain. In many maple cutting boards, for example, the strips are glued together randomly, resulting in mixed grain.

This distinction is partly one of appearance, but when building with or maintaining mixed grain wood projects, pay special attention to the ongoing moisture content (MC) levels.

Wood products manufacturers and woodworking hobbyists must understand how differently the grains shrink as MC changes. Wood shrinks about twice as much tangentially (in the direction of the growth rings) as it does radially (across the rings), and only slightly along the grain. So a flat grain board changes width more than an edge grain board as it dries or takes on moisture. This goes to the heart of a key concept in wood products manufacturing and woodworking: equilibrium moisture content (EMC).

EMC is reached when the MC in the wood is balanced with the surrounding RH, and a wood’s MC continues to change naturally as the RH changes. That’s why moisture meters for wood are critical for monitoring these changes and are a sound investment in overall MC management.

Too much, or even too little, MC can make adhesives less effective or even ineffective when gluing edge grain and face grain strips, as well as end-grain pieces. Too much difference in MC between wood pieces when manufacturing or crafting a fine piece of furniture or cabinet can lead to serious and possibly costly defects once in service.

Wood Moisture Meters

Regardless of the wood grain or the type of woodworking project, wood keeps absorbing and releasing moisture, and many common woodworking defects trace back to moisture. Those are critical reasons to have a high-quality moisture meter. Easy-to-use, accurate moisture meters for wood, such as Wagner Meters’ Orion^® 930 Dual Depth model, measure MC in a wide range of wood species, with specific gravity settings from 0.20 to 1.00.

Incorrect MC in your wood can lead to disappointing and possibly costly results, but using a quality wood moisture meter can give you confidence that your woodworking projects will turn out well.
