What is the size of a biscuit?
A biscuit is a thin, oval-shaped piece of compressed wood shavings, typically made from beech wood. When glued into slots precisely cut by the biscuit cutter, and the moisture from the glue causes the biscuit to swell and tighten the joint. Biscuits commonly come in three sizes: #0: 5/8 inch by 1 3/4 inches. #10: 3/4 inch by 2 1/8 inches.
How to choose correct size of wood biscuit for jointing?
How to choose correct size depends on the size of wood to be jointed. In most cases, #20 wood biscuit can be a good choice but for thinner material, small wood joint, small size would be a good choice, also.
How to choose biscuits according to the width of stock?
The differences in depth among the three is so small as to be insignificant. Thus, you can choose the biscuit according to the width of your stock. The #20 will be sufficient for perhaps 95% of the joints biscuits are commonly used for.
What size biscuits should I use for framing?
#10 biscuits are a standard size that works well for most framing projects. Hardware stores with limited woodworking supplies may stock #10 biscuits only. #20 biscuits are made for projects that will undergo considerable stress or that must bear a lot of weight.
How do I know what size biscuits to use?
What Size Biscuit to Use. As a general rule, try to use the largest size biscuit possible, as this will provide the greatest amount of strength to the joint. In most cases, use #20 biscuits, but when working on narrower material, switch to smaller biscuits where appropriate.
What size should biscuits be?
Gently pat the dough out into a 1/2-inch thick round, rotating often to ensure the dough isn't sticking. If you want REALLY tall biscuits, feel free to shape the dough to 3/4-inch or even 1-inch thickness instead. Use a 2-inch round biscuit cutter to push straight down through the dough to cut out circles.

How thick is a #20 biscuit?
3/4" thickThese are the standard size No. 20 biscuit that you will use for most woodwork where the piece the biscuit is going into is at least 3/4" thick.
What is the standard size for a biscuit cutter?
Though we tried every cutter in each set, most biscuit recipes call for a 2-, 2½-, or 3-inch biscuit cutter.
How wide is a biscuit joint?
Biscuit Joint Sizes and Settings The general rule of thumb is to use the largest biscuit possible, as larger biscuits allow for more surface area for glue. The most common sizes are: FF: ½” wide, 1 ⅜” long. 0: ⅝” wide, 1 ⅞” long.
How many biscuits should I use to join wood?
Two biscuits per foot is a great rule of thumb, but the goal is just to make the alignment task easier. So, if you have a couple of edges that are 24″ in length and are dead straight & perhaps you would only need two biscuits to do the job.
How thick should wood be for a biscuit joiner?
Typically, you'll center the slot in the wood. The joiner's base, when sitting on a flat surface, is preset to center the cut in 3/4"-thick stock.
Are biscuit joiners worth it?
Biscuits joints serve best as a quick and easy way to keep glue-up parts in alignment, and that they add appreciable pull-apart to strength joints that would be otherwise too weak to stand on their own – like butt joints and miter joints.
How tight should biscuits fit?
Biscuits should be somewhat loose; they are not designed to align parts. They are compressed during manufacture and are designed to swell with the application of water-based adhesive. Good quality biscuits should actually rattle just a bit in the slots.
Can you biscuit joint plywood?
However, with a biscuit joiner, clean, unobtrusive joints can be made in plywood, with no visible hardware and clean edges coming together. Whether joined together at 0 degrees, 45 degrees or 90 degrees, all joints are clean and tight, as well as being strong.
Can I use a router as a biscuit joiner?
If you want to make biscuit joints, you don't have to buy a biscuit joiner. In most cases, a router equipped with a 5/32-in. slot bit can cut perfect slots to fit the biscuits. Mark the biscuit positions on both adjoining boards as you would with a biscuit joiner.

What Is a Biscuit?
A biscuit is a thin, oval-shaped piece of compressed wood shavings, typically made from beech wood. When glued into slots precisely cut by the biscuit cutter, and the moisture from the glue causes the biscuit to swell and tighten the joint. Biscuits commonly come in three sizes:
What Size Biscuit to Use
As a general rule, try to use the largest size biscuit possible, as this will provide the greatest amount of strength to the joint. In most cases, use #20 biscuits, but when working on narrower material, switch to smaller biscuits where appropriate.
Edge-to-Edge Joints
The most common type of biscuit joints is edge-to-edge joints. This is often used for gluing up table tops of various width boards of the same thickness, where biscuits are used along the planed long edges of the boards.
Other Biscuit Joints
You can use biscuit joinery for a number of different types of joints. Smaller biscuits work well for strengthening miter joints and corner joints. Biscuits also work well for T-joints, where the end grain of one board is connected to the side of another board.
Biscuit Size
Joinery biscuits are all 5/32 inch thick, and are available in four width-and-length sizes:
Biscuit Spacing
As far as how far apart to space the biscuits, this is mostly a matter of preference, although there are some basic guidelines you can follow. The plate joints should be positioned so that the edge of the biscuit is two to three inches from the edge of the wood stock.
Biscuit Joinery Tips
Double up biscuits on thick stock. For example, when gluing up heavy stock for a thick tabletop, cutting double-wide slots and inserting pairs of biscuits will double-reinforce the edge-glued joints and make separation almost impossible.
Biscuiting basics
A biscuit joiner (also known as a plate joiner) cuts half-oval slots in mating workpieces; then you glue in a football-shaped "biscuit" and clamp the joint tightly. (Common biscuit sizes are shown at left .) Biscuits add strength to joints and assist you in aligning workpieces. Here's how to set up a joiner to cut a typical joint.
Step 1
Mark biscuit-slot locations across the joint between two boards you want to join. Mark the first board, then transfer to the second.
Step 2
Set the plunge-depth adjuster to match the biscuit size. For maximum strength, use the largest biscuit that fits your joint.
Step 3
Line up the slot-centering marks with your layout line. (Similar markings are on the base's bottom for using it vertically.)
Step 4
Typically, you'll center the slot in the wood. The joiner's base, when sitting on a flat surface, is preset to center the cut in 3/4"-thick stock.
Step 5
Finally, grip the joiner by the bale and the barrel (or handle), engage the power switch, and plunge the blade into the wood.
Step 6
After you've cut mating slots in your workpieces, add glue and biscuits and clamp the joint.
begin with the two slot test
A biscuit joiner should cut a slot slightly deeper than half the width of the biscuit you’re trying to fit. This space provides some wiggle room, but still ensures that about half remains on each side of the joint. Here’s how to check your joiner’s depth setting. First, make a test slot.
THE face-TO-edge BISCUIT JOINT
To cut the biscuit slots for the shelf, draw a pencil line across the inside face of the side and clamp the edge of the shelf against the line. Next, mark your biscuit slot marks on the top of the shelf. Resting the biscuit joiner on its base, place it on the side and cut the slot for the shelf as in Photo C.
THE END-TO-EDGE AND MITERED BISCUIT JOINTS
Biscuits are also an easy way to build mitered and end-to-edge frames that you would use for picture frames or for a cabinet’s face frame. In this case, biscuits are very useful because they are adding reinforcement to otherwise weak end-grain joints.
face miters
Face miters are A way to hide end-and edge-grain when making solid wood boxes or plywood cabinets, but long miters are tough to glue and tricky to reinforce. A few biscuits can solve both problems. They can register the ends so that the corners can’t slip during clamp-up and strengthen the otherwise end-grain joint.
offset joinery
There are times, as when joining a rail to a leg where you may not want a flush-fitting joint. Your biscuit joinser is equally adept at creating offsets. The trick is to use a spacer that the same thickness as your desired step back. The spacer-offset trick can be used with your biscuit joiner’s fence, or under the base of the tool, as shown here.
THE EDGE-TO-EDGE BISCUIT JOINT
You might want to think twice before using biscuits for solid-wood edge joints (See “Biscuits or No Biscuits?”). but biscuits are very useful for attaching solid wood edging to sheet goods, and also when you need to straighten out bowed boards. With practice, you may be able to biscuit an edge joint in less time than it takes to read how it’s done.
