This tip and trick video was created by Jodee at Inspire Woodcraft. It explores one of the most common questions in woodworking—where exactly should you cut in relation to your marking line?
Through practical demonstrations and clear explanations, Jodee breaks down not only which side of the line to cut on, but how to mark accurately, measure consistently, and improve your overall cutting precision.

Why Marking Matters More Than You Think
Marking isn’t just a step—it’s the foundation for every accurate cut you make. When you’re off by even a small amount, that error can multiply across your project.
In most cases, cutting on the waste side of the line is the safest approach. This method leaves your full measurement intact, preventing the common mistake of cutting a board too short.
The Difference Between Marking Tools
Not all marking tools are equal. In his video, Jodee compares carpenter’s pencils, mechanical pencils, and even ballpoint pens to show how line width can affect your results.
While some tools produce cleaner, finer marks, the real key is consistency and knowing how your tools behave. Even a thick carpenter’s pencil can be accurate if you’re familiar with its mark and apply it consistently.
How You Hold a Pencil Affects the Line
Something as simple as how hard you press or the angle of your pencil can change the line’s location by a noticeable amount. That’s why it’s important to develop repeatable habits.
Whether you use a knife, pencil, or pen, practice with your tool and pay attention to your grip and pressure. These small changes can lead to big differences when working with tight tolerances.
Tape Measures and Rulers Aren’t All the Same
Just like pencils, measuring tools vary in their accuracy and readability. Some tape measures have wider printed lines, which can make exact readings difficult.
For more precise work, a tape with narrow, fine lines can give you better results. Also, make sure the hook at the end of your tape is square against your board, or your starting point might already be off.
Don’t Skip Squaring the Board First
One of the most overlooked steps is squaring the end of the board before measuring. Construction lumber is rarely square on the end, and pulling a tape from a crooked edge will throw everything off.
Before you even think about cutting, take a moment to trim and square the end of the board. That small habit can eliminate headaches later.
Using the Square the Smart Way
When extending a mark across a board, many woodworkers place the square first and then mark. Jodee suggests a better method: hold the pencil at your mark, then slide the square into place.
This technique reduces guesswork and helps keep your mark exactly where it needs to be. It’s a small change that can boost your accuracy every time you measure.
When to Ignore the Line Entirely
In some setups, like with a miter saw, Jodee explains that the most accurate way to cut is to eliminate the line completely. By knowing the exact distance from the fence to the blade, you can mark your cut based on that reference alone.
This is especially useful when working with irregular stock, where a line may be distorted due to warping or inconsistent edges. Focusing on the mark, rather than the line, removes a layer of confusion.
Achieving Better Joinery Fits
When it comes to joinery, the level of precision needed increases dramatically. Instead of a pencil, a knife mark or sharp mechanical pencil gives a thinner line, making it easier to cut exactly to the intended edge.
For recessed fits or detailed cuts, being off by even 1/64″ can result in loose joints. A fine marking tool, paired with the right measuring and cutting habits, makes a huge difference.
Additional Tools That Improve Accuracy
Jodee also recommends using marking gauges or calipers when working on repeatable cuts. These tools provide consistent references, particularly useful when setting up for dovetails, dados, or other joinery.
While they may not be necessary for every project, they’re worth considering if you’re trying to improve the precision and consistency of your woodworking.
Building Better Habits for Long-Term Accuracy
The video isn’t just about tools—it’s about building better habits. Understanding where to cut, how to measure, and when to square up material all add up to better outcomes.
These habits take time to develop, but once they’re in place, they lead to fewer mistakes and less wasted material. Whether you’re just starting out or refining your techniques, Jodee’s tips offer a reliable guide to working smarter in the shop.
