Planer vs Jointer (Side-by-Side Comparison)

Now that we have a good understanding of what a planer and jointer are, let’s compare them side by side across various aspects.


The planer is mainly used for achieving uniform thickness throughout the boards and creating parallel surfaces. On the other hand, jointers are primarily used for flattening and squaring the edges of boards, creating flat and straight surfaces.


In terms of the blades, planers have the blade positioned above the table and cut from the top, while jointers have the cutting knives embedded in the table, and the wood passes over them.

Surface Flattening & Smoothness

Planers ensure consistent flatness and smoothness across the entire surface of the board. Jointers, on the other hand, achieve a perfectly flat surface, but the limited width they can handle may result in inconsistent smoothness.

Edge Straightening and Squareness

This is where jointers shine. They provide precisely square and straight edges, making them ideal for edge joining boards smoothly. Planers, however, cannot effectively square the edges of a board on their own.

Thickness Control and Accuracy

Planers offer greater control over thickness adjustment, allowing for precise dimensioning. Jointers, on the other hand, do not provide control over thickness and are mainly focused on surface flattening.

Dust Collection & Safety

Planers are often equipped with built-in dust collection systems and safety features like blade guards. Jointers commonly include safety features such as blade guards, but their dust collection may not be as efficient.
