carpentry terms

As the world of carpentry is vast and intricate, beginners can easily become overwhelmed by the terminology used by seasoned professionals. Understanding basic carpentry terms is crucial for anyone starting in this field.

This article will serve as a comprehensive glossary of common carpentry terms, helping newcomers familiarize themselves with the language of the craft.

Commonly Used Carpentry Terms

Let’s dive into some of the terms you’ll commonly encounter in the world of carpentry:


A bevel is an angle that is cut on the edge of a piece of wood that isn’t a 90-degree angle. This type of cut is often used for fitting corners together more tightly or for decorative purposes. For an in-depth look at creating precise bevel cuts, check out our guide on mastering the saw.


A joist is a horizontal structural member that supports a ceiling or floor. Joists are part of the framing process and are fundamental in creating the substructure of a building.


In carpentry, a stud refers to the vertical framing member in wall construction. They are a crucial component of the framework, providing stability and serving as a nailing base for wall coverings.


A rafter is a sloped structural member that extends from the ridge or hip down to the wall plate. These beams support the roof deck and shingles of a building.


The subfloor provides a flat, stable base for the finish floor and is attached to the floor joists. It is often made of plywood or oriented strand board (OSB).


Rough-in refers to the initial stage of a construction project which includes the installation of basic plumbing, electrical, and HVAC without the finishes. For those interested in the intricacies of home repairs and this phase of construction, a detailed discussion can be found on carpentry home repairs.


Shiplap is a type of wooden board used commonly as exterior siding in the construction of residences, barns, sheds, and outbuildings. It has a rabbet (groove) cut into the top and bottom which allows the pieces to fit snugly together, forming a tight seal.


The kerf is the channel or cut produced by a saw blade. It is also the measure of the width of the cut; knowing the kerf allows you to make precise adjustments where tight fitting is required.


When something is ‘plumb,’ it means it is perfectly vertical or straight up and down. A plumber’s bob or a spirit level may be used to ensure that elements are plumb.


Being ‘level’ is akin to being perfectly horizontal or flat. Carpenters often use a spirit level to ensure surfaces are level to achieve a balanced and accurate construction.

Miter Cut

A miter cut is an angled cut that is typically made at a 45-degree angle, and used for corners, like picture frames or door trims. The basics of making miter cuts can further enhance your understanding of this technique.


A dado is a groove cut into the surface of a piece of wood that can house another piece of wood. This joint is frequently used in cabinet and bookshelf construction.


Similar to a dado, a rabbet is a recess or groove cut into the edge of a piece of wood. It is commonly used at the edge of a board to form a joint with another piece.


In woodworking, the grain refers to the orientation of the wood-cell fibers. Being mindful of the grain is vital when planning, cutting, or finishing wood.

Rip Cut

This cut is made along the length of the wood, parallel to the grain. It is usually made to reduce a piece of wood to the needed width.

Cross Cut

Opposite to the rip cut, a cross-cut is made across the grain of the wood. It is typically used to cut a piece of wood to the desired length.

End Grain

The end grain is the surface of the wood visible when it is cut across the growth rings. It can be more difficult to work with but is essential for certain joinery techniques.


A fastener is a hardware device that mechanically joins or affixes two or more objects together. Understanding the various types of fasteners is key for any carpentry project; delve into the array of options in our understanding fasteners guide.


In woodworking, a spline is a thin strip of wood inserted into aligned grooves or slots in two adjacent pieces of wood to produce a strong joint.


A truss is a framework, typically consisting of rafters, posts, and struts, supporting a roof, bridge, or other structure.


Veneer refers to thin slices of wood, usually thinner than 3 mm (1/8 inch), that are typically glued onto core panels to produce flat panels such as doors, tops, and panels for cabinets.


The workpiece is the piece of wood that is being cut, shaped, or finished in a woodworking project. Being familiar with it is quintessential as it’s the foundation of all your work.
