Shaker Cabinet Doors Made to Your Size List
Five-piece Shaker doors with square edge frames and flat recessed panels, paint grade or stain grade, made to a cut list with hinge boring and matching drawer fronts.
A Shaker door is a frame of two stiles and two rails around a flat, recessed center panel, with a square inside edge and no decorative profile. It is the most ordered cabinet door style in North America, so cabinet shops and kitchen brands buy it from door plants by the thousand instead of making it in-house. The plant works from a cut list: each door with its finished width and height, species, panel type, hinge boring and finish.
The price depends mainly on the frame joint, paint grade or stain grade material and the finish. A paint grade door with an MDF panel, primed and bored, is a very different product from a stain grade white oak door with a veneered panel and a factory finish, even at the same size. Odd sizes, very tall doors and narrow drawer fronts also add cost because they need more setup and more care to stay flat.
Species and panels
- Hard mapleHard and fine grained. The standard for stain grade light doors and for durable paint grade frames.
- PoplarLow cost and smooth under paint. Softer, so it dents more than maple.
- MDFFor panels and for paint grade frames or one-piece doors. Stable and smooth, but heavy and weak at screws near the edge.
- White oakStrong grain, often rift or quarter sawn for Shaker doors. Common for stained and natural finishes.
- Red oakOpen grain with a pink tone. A lower cost stain grade option in North America.
- CherryFine grain that darkens with light. Used for traditional stained kitchens.
- PlywoodVeneered plywood panels for stain grade doors, with a face veneer matched to the frame species.
Types of Shaker cabinet doors
Name the type on the RFQ. Factories that make one type well do not always make the others.
| Type | What it is | Fits |
|---|---|---|
| Cope-and-stick 5-piece door | Rails are cut with a cope on the ends that fits the groove along the stile edge. The joint is a short stub tenon glued into the groove. | Most production Shaker doors. Fast to run and strong enough for standard sizes. |
| Mortise-and-tenon 5-piece door | Rails have full length tenons glued into mortises in the stiles, sometimes pinned. | Tall pantry doors, inset doors and heavy doors where a stub tenon is not enough. |
| One-piece MDF Shaker door | An MDF slab with the recessed panel routed by CNC, so there are no frame joints. | Paint grade lines where joint cracks are not accepted and cost matters most. |
| Matching drawer fronts | Five-piece fronts with the same frame width, or slab fronts for short drawers. | Every kitchen. Drawer fronts below about 5 to 6 in tall are often made as slabs, typical. |
| Slim Shaker door | A Shaker door with narrow frames, about 1 to 1-1/2 in wide, typical. | Modern kitchens and furniture fronts. Narrow frames need tighter joints to stay strong. |
Typical specifications
Starting points used across the trade. Your drawing sets the real values, and each factory confirms what it can hold on the quote.
| Spec | Typical value | Note |
|---|---|---|
| Stile and rail width | 2-1/4 to 3 in, typical | State one width for all doors or give it per door. |
| Door thickness | 3/4 in (19 mm), some lines 7/8 in, typical | Must match the hinges and the cabinet design. |
| Panel | About 1/4 in MDF or veneered plywood, recessed about 1/4 in, typical | Solid wood panels must float in the groove to allow wood movement. |
| Size tolerance | About ±1/32 in (±0.8 mm) on width and height, typical | Give finished door sizes, not cabinet openings. |
| Flatness | Warp within about 1/16 in over the door, typical | Tall and narrow doors need extra care. State a limit for doors over about 40 in. |
| Hinge boring | 35 mm cup holes, about 3 to 6 mm from the door edge, typical | Give the boring pattern, cup depth and distance from top and bottom. |
| Moisture content | 6 to 9 percent for frames, typical | Match the market. Very dry homes in winter cause joint cracks. |
Typical values, not a guarantee. Confirm every value that matters to you on the quote and the approved sample.
How it is built
- Paint grade framesMDF frames, or poplar or hard maple. Poplar is cheap and smooth under paint but soft. Maple is harder and dents less. MDF frames do not move with humidity.
- Stain grade framesHard maple, cherry, white oak, red oak or walnut, color and grain matched on each door. Quarter sawn or rift oak is common for a straight grain look.
- PanelsMDF for paint grade. Veneered plywood or veneered MDF for stain grade, so the panel matches the frame and stays flat. Solid wood panels float on spacers and must be prefinished before assembly.
- Overlay and sizingFull overlay, partial overlay or inset decides the door size. Full overlay doors are usually the opening plus about 1/2 to 1-1/4 in, depending on the reveal. The cabinet maker should do this math and send finished sizes.
Finish options
- Unfinished, sandedFor shops that finish in their own booth. Ask for 150 to 180 grit and packing that keeps doors flat and clean.
- PrimedPaint grade doors with one or two primer coats, sanded and ready for topcoat. Ask which primer so your topcoat is compatible.
- Factory finishedPainted or stained and sealed with a catalyzed lacquer or conversion varnish, matched to an approved sample. Ask for the finish system and sheen.
How Shaker cabinet doors are made
The usual process chain, from dried lumber or panels to packed goods. Ask which steps happen in-house and which go out to another plant.
- 01Kiln dryingFinal moisture content, internal stress and how much the part moves after delivery.
- 02Rough millingHow much clear wood you pay for, which defects reach your parts and how evenly the color runs.
- 04Planing and mouldingFinal thickness and width, how square and straight the part is and how much sanding the surface needs.
- 05CNC routingShape accuracy, hole positions for hardware and how well parts from different batches fit together.
- 09Joinery and assemblyHow strong and rigid the product is, how square it stands and how it ships.
- 10Sanding and finishingColor, sheen, smoothness and how well the surface resists heat, water and wear.
- 11Inspection and packingWhether the goods that leave the factory match the order, and whether they arrive in the same condition.
Who orders Shaker cabinet doors
Cabinet shops often order per kitchen, from about 20 to 60 doors, while brands order standard sizes by the container. Many door plants set a minimum per order or per species and finish, and quote odd sizes and tall doors by size band.
Cabinet shops
Order doors per job from a cut list and build the boxes themselves. They need exact sizes, correct boring and fast repeat orders for missing doors.
Kitchen and RTA cabinet brands
Buy standard door sizes in volume for a fixed range. They care about color match across lots and packing that survives parcel shipping.
Remodelers and refacing companies
Buy doors and drawer fronts to fit existing cabinet boxes. They need custom sizes and matching veneer or paint for face frames.
Rules that may apply
- TSCA Title VI applies to MDF and plywood panels and frames sold in the US, and CARB Phase 2 in California
- EU buyers often ask for E1 or lower formaldehyde class panels, so state the class you need
- EUDR due diligence for wood placed on the EU market
- FSC chain of custody only if you plan to make an FSC claim on the doors
What to send for a quote
With these points stated, every matched factory quotes the same product.
- A cut list with finished width and height for every door and drawer front
- Frame width, thickness and joint type: cope-and-stick or mortise and tenon
- Species and grade, or MDF, and the panel material
- Overlay type and hinge boring pattern, or no boring
- Finish: unfinished, primed or finished to a color sample
- Packing per door, per job or per carton, with labels by cabinet number
What to check on samples
Approve one sample in writing and keep it as the reference for every shipment.
- Width, height and squareness on a sample of doors from every job
- Flatness on tall doors and on doors with solid panels
- Hinge cup position and depth against the boring drawing
- Joint fit and glue line at the frame corners before finishing
- Color and sheen against the approved sample under the same light
Where orders go wrong
The problems that cost buyers of Shaker cabinet doors the most time and money, and how to head them off in the RFQ.
- Cracks at painted frame jointsSolid wood stiles and rails move with humidity, so a hairline crack at the rail joint is normal on painted 5-piece doors. Agree on whether it is a defect, or order MDF frames or one-piece MDF doors.
- Opening sizes instead of door sizesIf you send cabinet openings, the plant has to guess the overlay and reveal. Send finished door sizes so there is one source of truth.
- Narrow drawer fronts as 5-pieceOn short drawers the panel becomes a thin strip and the rails look heavy. Decide a height below which drawer fronts are slab, and put it in the order.

What is the standard frame width on a Shaker cabinet door?
Most Shaker doors use stiles and rails about 2-1/4 to 3 in wide on a 3/4 in thick door. Slim Shaker styles go down to about 1 to 1-1/2 in. Keep one width across a kitchen so doors and drawer fronts line up.
Paint grade or stain grade: what is the difference?
Paint grade doors use MDF, poplar or maple with MDF panels, since paint hides grain and color changes. Stain grade doors use maple, cherry or oak frames with matching veneered panels, sorted for grain and color.
Why do painted Shaker doors crack at the corners?
Solid wood frames expand and shrink with humidity, which opens a hairline line in the paint at the rail joint. It is normal on painted solid wood doors. MDF frames or one-piece MDF doors avoid it.
Can the factory bore the doors for hinges?
Yes, most door plants bore 35 mm cup holes for concealed hinges. Send the boring pattern (distance from the edge, cup depth and distance from top and bottom) and say which side each door hinges on.
Do I send door sizes or cabinet opening sizes?
Send finished door sizes. The overlay and reveal depend on your cabinet design and hinges, so the cabinet maker should work them out. This avoids doors made too large or too small.
