How to use a marking gauge

Updated: 22 October 2026

The line you just scribed has torn out, wandered, or sits a couple of millimetres from the rule. This is how to use a marking gauge: set the fence, keep it on the whole edge, and let a sharp cutter mark lightly. That table is the [marking gauge comparison](/hub/measuring-and-marking-tools/marking-gauge). Choosing pin, wheel, or mortice starts on the [marking gauge buying guide](/hub/measuring-and-marking-tools/marking-gauge/sub/marking-gauge-buying-guide). Peter F. wrote this from BBC Bitesize, Paul Sellers, and Lee Valley’s UK guide on 21 October 2026. A qualifying purchase can earn a commission at no extra cost to you.

Set the distance

Set the fence from the workpiece or from a steel rule, tighten the screw, and measure again. Reviews in this comparison say the setting moves after the screw is tight. The second measurement is the one you cut to. The Stanley 2-47-064 prints steps of 2 mm, which reviewers call too coarse, so they use a ruler. QWORK claims that a knurled nut moves the fence by 0.2 mm. The cutter, once the distance is honest, sits on pin marking gauge vs wheel.

Keep the fence on the edge

Press the stock against the whole reference edge, not the arris alone. If only the corner touches, the line walks. Lee Valley’s UK guide asks for light lateral pressure. BBC Bitesize says the same thing: keep the stock flat and run the spur lightly. A triangular or round head can roll. Stanley reviewers describe a missed line for that reason. The Clarke Brothers listing claims a flat spot so the body stops rolling.

Pin gauges

Trail the pin so the point follows the stroke. An upright spur lets the grain steer the line, which is the distinction Paul Sellers makes. Take several light passes. One heavy pass tears the face at the cross-grain end of a rail. These sources do not fix a projection in millimetres. If you have to force the pin, Lee Valley treats the cutter as dull. Two pins set to a chisel stay on the mortice gauge page.

Wheel gauges

You can push or pull a wheel. If the disc tracks the grain, reverse the stroke. On end-grain oak, Paul Sellers has gone back to a pin. A wheel is the cleaner cutter across the grain in Lee Valley’s UK guide, not a promise on every board. If the line is a bruise, the wheel is blunt. Fit the spare if the box included one. The Clarke Brothers box lists two replacement cutters. The YOSELIN wheel lists one extra blade.

When to stop

Stop when the tool cannot do the job it was sold for. A stock that will not slide, or a lock that will not hold, is a fault to raise with the retailer under the Consumer Rights Act 2015, section 9. Amazon’s UK help excludes a business purchase. Sanding a sticky beam is fettling. A seized gauge is a return. Hand structural timber, a stair, or a fire door to a joiner. A household shed sits outside the employer’s duties in PUWER 1998.

Common questions

Do I push or pull a marking gauge?
Both directions show up in Paul Sellers’ account and on the UK Workshop technique thread. Trail a pin so the point follows the stroke, with light pressure, whether your hand is moving away from you or toward you. A wheel can be pushed or pulled as well. If the disc starts to follow a coarse grain line, reverse the direction and keep the fence on the whole edge. These sources do not name one legal direction.
Why is the line fuzzy?
A fuzzy line usually means the cutter is tearing fibres or the fence is rocking on the corner. Trail the pin, keep the stock flat on the whole edge, and take a lighter pass. Across the grain, a pin often tears where a sharp wheel would sever. If the mark is only a dent, file two faces of a pin, or fit a spare wheel.
How far should the pin stick out?
Far enough to touch the wood when the fence is flat on the edge, and short enough that you are not burying the spur. These sources do not give a projection in millimetres. If you must lean hard before you see a line, the pin is dull or it is standing upright. File a short edge on two faces, as BuildWiz describes, and try a scrap.
Should I trust the millimetre marks?
Use them as a reminder after you have set the fence from a rule or from the workpiece. The Stanley gauge in this set is marked in 2 mm steps, which reviewers call too coarse, and the printing can rub off. QWORK claims 0.2 mm from a knurled nut, and a review says the nut and the stem do not agree. Lock the fence, measure again, and cut to the second reading.
What do I do if the stock will not move?
If the beam is only sticky with varnish, ease it with a light sand and wax, which is the fettling Sellers describes for a new wooden gauge. If the stock will not slide, or it slides and will not lock, stop. That is a satisfactory-quality question under the Consumer Rights Act 2015, section 9, taken up with the retailer.
When is the wheel blunt, and where do I stop at the end of the board?
The wheel is blunt when it indents and leaves fibres standing, and when you have to force the fence to see a line. Check the fence is on the whole edge before you blame the cutter. Then fit the spare if the box included one. Stop short of the end so the cutter does not splinter the arris. BuildWiz uses about 10–15 mm as its own figure.
