Shaker Cabinet Door Calculator

Shaker Cabinet Door Calculator

Size finished cabinet doors, rail and stile cuts, flat panel cuts, overlay or inset gaps, material totals, and waste for real shaker cabinet layouts.

1Cabinet presets

Choose a common cabinet opening, then adjust the measurements for the actual case, face frame, and hinge style on your bench.

2Door inputs

Overlay adds to the opening; inset subtracts the perimeter gap.
Used for board footage, weight, and movement notes.
Clear cabinet opening or desired custom door width.
Measure height at both sides and use the tighter value.
Ignored for inset and custom finished door modes.
Inset perimeter gap or center gap between paired overlay doors.
Paired doors split the total width and keep a center reveal.
Used when door count is 2 or more across one opening.
Vertical frame member width, usually 2 to 2 1/2 in.
Horizontal frame member width, often matching the stiles.
Visible shadow step from frame opening to flat panel edge.
Amount of panel hidden in the grooves on each edge.
Added twice to rail cut length for cope-and-stick doors.
Typical hardwood shaker frames are 3/4 in thick.
Flat plywood or MDF panel thickness.
Adds cutoff, milling, defect, and layout allowance.
Displays shop-friendly cut dimensions without changing formulas.
Always verify hinge overlay, door swing clearance, and saw setup before cutting. Never mill rails or stiles shorter than your joinery system safely allows.

5Workshop tips

Tip: For replacement doors, measure each opening and each existing door. Cabinets that look identical often vary by 1/16 in after years of settling and face-frame sanding.
Tip: Mill extra rail and stile stock before cutting final lengths. Shaker doors look cleaner when all matching doors share the same rail width and panel reveal.

Shaker cabinet doors includes a frame and an center panel. The construction of Shaker cabinet doors utilize a frame and panel method to maintain the low weight of the cabinet doors. Shaker cabinet doors require precise measurement for the cabinet doors to fit into the cabinet.

If the measurements for the Shaker cabinet doors isnt correct, then the Shaker cabinet doors will either become stuck within the cabinet or the gaps between the cabinet doors will be even more. The calculator allow you to input the size of the cabinet opening, the chosen fit for the Shaker cabinet doors, and the width of the frame. Based on these measurements, the calculator can tell you the dimension that the Shaker cabinet doors should be.

How to Measure and Make Shaker Cabinet Doors

The overlay measurements for the Shaker cabinet doors will allow you to determine how much of the face frame the cabinet doors will cover and where the hinges will be located on the cabinet doors. If you change the overlay measurement, the swing of the cabinet doors will change. For inset Shaker cabinet doors, the gap that you enter into the calculator will allow the cabinet doors to open and close without scrape against the frame.

This gap will control the appearance of the cabinet doors. The components of the frame for the Shaker cabinet doors are the rails and the stiles. The width of the rails and the stiles will determine the width of the frame that will be visible on the Shaker cabinet doors.

The rails will need tenons, and the tenons will add to the length of the rail. If the tenons are too long, then the opening in the Shaker cabinet doors will be too small for the panel. If the tenons are too short, the cabinet door joints will be weak.

The center panel need a groove to recieve the panel. If the panel is not given enough space within the groove, then the panel may push out of the cabinet door. The panel may also have too much space within the groove, which will make the cabinet doors look heavy.

The type of wood that you use will impact the weight of the Shaker cabinet doors and how easily you can mill the wood into the cabinet doors. If you use a dense hardwood for your cabinet doors, the cabinet doors will be heavy. The heavy Shaker cabinet doors will require the cabinet hinges to have more strength than those that open lighter cabinet doors.

If you use a softer type of wood, the Shaker cabinet doors will be easier to mill but may bruise during the assembly of the cabinet doors. To compare the weight of the cabinet doors, you can use the wood calculator to determine the density of the wood. When making Shaker cabinet door sets, you must account for the center gap between the two cabinet doors.

This gap will allow the cabinet doors to not rub against each other when the humidity level increase. The width of the center gap will impact how the cabinet doors look. If the gap is too wide, the cabinet doors may appear separate from each other.

If the gap is too narrow, the cabinet doors will become stuck when the humidity increases in the space where the cabinets is installed. The other consideration is the scale of the stiles used on tall pantry cabinet doors. If the pantry shelves have tall doors with wide stiles, this might look incorrect next to other cabinet doors with narrow stiles.

Always include a waste allowance when calculating the amount of wood that you will need for your Shaker cabinet doors. A waste allowance will protect you from running out of wood. Some of the wood will be lost to the tenons; some of the wood may also be lost to defect in the boards of wood that you use to make the Shaker cabinet doors.

The reference tables included with the calculator show typical widths for the rails in the cabinet doors and the sizes of the cabinet opening. These tables will allow you to compare the dimensions of your cabinet doors to other cabinets in kitchens. These tables also include information about the behavior of the different types of wood after you apply a finish to the cabinets.

This information may help you to find wood that matches the color of the existing cabinet doors in your kitchen. A common mistake with Shaker cabinet doors is to measure only one side of the opening in the cabinet. The measurements for the cabinets may not be square; over time, the cabinets may settle or the face frames may be sanded unevenerly.

Therefore, you must take the measurement of the height of the opening on both side of the cabinet and measure the width at the top and the bottom of the opening. The smallest measurement that you record for each dimension will allow you to calculate the size of the Shaker cabinet doors. Based on your measurements, the wood calculator will produce a cut list of the dimensions of the piece of wood that you will need to purchase.

The cut list will only be accurate if your measurements are accurate. After you have milled the individual part of the Shaker cabinet doors, perform a dry fit of the cabinet doors. A dry fit will allow you to ensure that the panel fit into the groove of the Shaker cabinet doors and that the cabinet doors will sit flat on the door frame.

You can make adjustment to the cabinet doors during a dry fit. However, making adjustments after you have glued the cabinet doors to the tenons will be much more difficult. A dry fit will allow you to create cabinet doors that is simple in design and that maintain their shape despite changes in the humidity levels in the environment and the use of the cabinets.

You should of checked the dimensions twice. It is important to ensure you’re measurements are correct.
