Best Wood for Kitchen Cabinets, and When It Barely Matters

Somebody handed me a list with six wood species on it, ranked and priced from one dollar sign to four. Cherry near the top. Birch at the bottom, alone in the cheap column.

I went and looked up the actual hardness figures, because I wanted to know whether the list was engineering or marketing. Cherry is the softest wood on it. Birch is harder. So the best wood for kitchen cabinets depends on a question that list never asks.

That question, the numbers behind it, and the point where we stop being the right shop for you.

Decide the Finish Before You Decide the Species

Here is the disclosure up front, the way we do it around here. I am a part owner of a company that sells cabinets in exactly one wood. I am also the person who joined this business as a skeptic and went looking for reasons not to, so I am going to give you the version with the numbers in it and let you do what you like with it.

Now, the part that saves most people an afternoon. Ask yourself whether the doors are going to be painted or stained. Everything else follows from that, and almost nobody frames it that way, because a species list is easier to sell from than a finish decision is.

• If you are painting, the grain goes under primer and stays there. What you are choosing is a paint-grade wood, which in practice means hard maple, soft maple, birch, poplar, or a fibreboard door. The differences that matter now are whether the grain telegraphs through the finish, how well the surface takes a primer, and how the door is built. Red oak is the one to strike off immediately: its open grain shows through paint unless the shop fills it first, and most will not. Poplar has green and brown streaks that can bleed through a light colour.
• If you are staining, the species is the whole job. Grain pattern, colour, how the wood takes pigment, and how it looks in ten years are all species properties, and none of them can be added later. This is where the price tiers start to mean something real.

Painted doors outsell every other finish, and have for years. Which means a good deal of the species argument on the internet is being had by people who have already decided it does not apply to them.

Read the Hardness Numbers Before the Price Tier

Cabinet marketing loves the word durable and hates publishing a figure. There is a figure. Wood hardness is measured as side hardness under a standard test, and the reference values live in the Wood Handbook published by the Forest Products Laboratory, which is a United States Forest Service body. No Canadian agency publishes an equivalent table, so American figures are what everyone on both sides of the border is quoting, whether or not they say so.

Here are the six species you will be offered, sorted hardest to softest, with the shrinkage figures from Chapter 4 of the same Handbook alongside them.

Read the first two columns against each other and the tier list starts looking odd.

Walnut and cherry sit at the top of nearly every price ranking published and at the bottom of the hardness table. Cherry measures 950 lbf against maple’s 1,450, a third less, and it costs more. Hickory is the hardest by a distance, and it is priced in the middle, or sometimes described as a budget wood, depending on which page you land on.

None of that makes cherry or walnut bad. They are gorgeous, they are scarcer, and people want them, which is what a price tier is actually measuring. Just be clear about which of those two things you are paying for.

The gap people assume is enormous mostly is not. Maple to birch is 1,450 against 1,260, a difference of about 13 percent. Side hardness is measured by pressing a steel ball into a small clear sample, and a cabinet door is a vertical surface that gets touched rather than a floor that gets walked on. Thirteen percent of that figure is nothing you will ever find with a fingernail.

Compare How Each Species Moves Through the Year

Hardness gets all the attention, and movement causes more of the problems.

Wood changes size as the air around it dries out and dampens up, and it does not change size evenly. It moves most around the growth rings, roughly half that across them, and almost none along the length of the board. The Wood Handbook’s shrinkage figures in the table above are the standard reference, measured from green to oven-dry, and the useful thing is the ratio between the two directions rather than either figure on its own.

• A high ratio means the board wants to cup.
• A low ratio means it stays flatter and moves more evenly.

Sort that column, and you get an answer nobody puts in a species listicle:

• Red oak has the highest ratio of the six at 2.15, and sugar maple is close behind at 2.06.
• Yellow birch has the lowest at 1.30, which makes it the flattest-behaving of the common cabinet woods.

Being honest about the other half of that, because it cuts against us. Birch also has the highest total volumetric shrinkage of the six at 16.8 percent, ahead of hickory at 16.7 and well ahead of cherry at 11.5. Birch moves a lot. It just moves evenly, which is what keeps a door flat. Anybody telling you birch is dimensionally superior, full stop, is quoting half a table.

Where this shows up in a real house is a painted door in February. Most cabinet doors are five-piece, meaning two vertical stiles, two horizontal rails, and a center panel sitting loose in a groove so it can move. When the panel shrinks away from that frame, the paint film spanning the joint has to tear somewhere. The trade calls the fine line it leaves a witness line. Cosmetic rather than structural, and the single most common thing people are unhappy about a year into a painted kitchen.

Two things reduce it, and neither is the species on the invoice: a center panel made of a material that barely moves, and a finish applied to every face of the door before it goes together. That argument runs longer than this article, and we have made it separately, alongside what happens to a vinyl-wrapped door.

Question the Birch Dismissal

Every page ranking for this search puts birch in the cheap column. One of them leaves it out of the species list entirely. Even the Canadian Kitchen Cabinet Association, which is the national trade body and generally worth reading, describes birch on its own consumer page as “a soft, lush wood which stains extremely well.”

Half of that is right. Birch does take a stain well, and it is a warm-looking wood. The soft part does not survive contact with the hardness table: yellow birch measures 1,260 lbf against red oak at 1,290, so the two are effectively level, and both sit far above cherry and walnut. The same page also calls oak “the toughest of the hardwoods,” which hickory beats by nearly 600 lbf. Old consumer copy repeats itself for years, and this is what happens.

The real case against birch is narrower, and it is worth knowing:

• Birch blotches under a dark stain unless it is properly conditioned first, exactly like maple does.
• It has less figure and less character in the grain than oak or hickory, so if you want a door with something going on in it, birch is a quiet choice.
• And “birch” on a spec sheet covers more than one species. Yellow birch is the cabinet-grade one in North America, and the figures above are its figures. Paper birch is a different and softer wood. Ask which one you are getting, including from us.

Worth separating two things that get blurred whenever a Canadian company mentions Canadian wood. Birch and maple both grow across this country, and Natural Resources Canada records that Canadian hardwoods are used mainly for “non-structural, visual applications such as furniture, flooring and cabinet doors.” That is a fact about the forest. It says nothing whatsoever about where our supply comes from, and we are not going to let you infer that it does. BluePrint is a dealer; the cabinets are manufactured overseas, and Patrick has written the long version of that on the site under the origin question.

If you want to look up a species yourself before somebody quotes you on it, the NHLA hardwood species guide carries a reference card for each of the common cabinet woods. NHLA is a trade association based in Memphis, Tennessee, and Canadian mills grade to its rules because this country never wrote its own for hardwood.

Know When We Are the Wrong Shop

Patrick runs the product side here. When I asked him to summarise the range in one line, he said: one wood, eight looks.

Unpacked, that means five stained styles built as a solid birch frame around a center panel of HDF, a high-density fibreboard, carrying a birch veneer. Then three painted styles with HDF in both the frame and the panel and no solid wood in them at all. Each style publishes its own specification under the eight door styles, and the finishes sit together on the shaker page.

So here are the buyers we are wrong for, plainly.

• You want white oak. It is the species of the moment, and we do not carry it in any finish.
• You want walnut, cherry, or hickory. Same answer. If the grain is the point of your kitchen, we are not your shop.
• You want a solid wood center panel in the door. No door in our range has one.
• You want a species matched to existing millwork or a floor. We have birch, and birch either matches or it does not.
• You need a cabinet at a width we do not stock. Ours come in 3″ increments, and an individual unit cannot be altered, which is the same limitation set out on the cabinets described as custom page.

Where we do fit is narrower, and the shape of it is worth stating exactly. A painted kitchen, where the species argument was mostly theoretical to begin with. Or a stained kitchen where one of five birch finishes is the look you want. Read the figures earlier in this article against that door carefully: they describe solid birch, so on our stained styles they apply to the frame around the panel and not to the panel itself. And they apply at all only if the birch in question is yellow birch, which is the cabinet-grade birch in North America and the one we are asking our own supplier to put in writing. Our layouts with the dimensions attached show what the finished thing costs.

Frequently Asked Questions

Narrow Your Shortlist to Two

Answer the final question and six species become two or three in about a minute. Painting? You are choosing between hard maple, birch and a fibreboard door, and the deciding factors are how the door is built and how it is finished rather than the name of the tree. Staining? Pick on grain and colour, since that is what you are actually buying, then check the hardness column so a soft wood does not get sold to you as a tough one.

Two things to ask whoever is quoting you. The species by its full name, yellow birch or hard maple or northern red oak rather than “birch” or “maple”. And what the door’s center panel is made of. A shop that answers both without going to look things up is a shop that knows what it is selling.
