Repeating hinge gains or latch recesses in door jambs calls for a layout method that stays consistent without turning each cut into a fresh measuring exercise. The useful tools are simple: a sharp pencil or knife, a rule, a square, and a depth gauge. For repeated work, a story stick or a purpose-made hinge template can save time, but only if it registers reliably against the jamb.
Choose a layout method that suits the run
For one or two doors, a tape measure, combination square, and marking knife are usually enough. For several matching doors, make a story stick from straight scrap or use a hinge template. The key is to transfer every position from the same reference—typically the top of the jamb or a consistent floor datum—instead of measuring each opening independently. Small measuring errors accumulate: a hinge 2 mm out of position may still work, but mismatched hinge lines are easy to see.
Before marking, confirm the hinge size, the jamb and door relationship, and which side the door swings toward. Check whether the hinge leaf is square-cornered or rounded. A template made for one corner style may not suit the other, and a mortise that is too large leaves a visible gap around the leaf.
Comparison of layout tools
| Tool | Best for | Strength | Common drawback |
|---|---|---|---|
| Tape measure and combination square | One-off work or occasional repairs | Inexpensive and versatile | Repeated readings can drift |
| Story stick | Several identical jambs | Transfers a set of positions quickly | Only as accurate as its reference ends and marks |
| Hinge marking template | Repeated hinge gains of one size | Locates the outline consistently | May not fit every hinge or jamb profile |
| Marking knife and square | Clean, precise cut lines | Gives a crisp edge that resists chisel breakout | Slower than pencil for rough layout |
Use a story stick for repeated positions
A story stick is a strip of straight, stable stock long enough to reach between the reference point and the furthest hinge. Mark the top or bottom of each hinge position directly on it, then label the reference end clearly. A 6 mm-wide strip of plywood or hardwood is easier to handle than a floppy offcut; check that it is straight and not twisted before relying on it.
Set the stick against the same datum on each jamb and transfer the marks with a square. Don’t flip it end-for-end between openings unless you have marked both ends and accounted for the change. A common failure is making a good stick but registering it against different points on different jambs—such as the floor on one opening and the head on another. That produces consistent marks relative to inconsistent references.
For a small number of doors, a combination square is a practical purchase because it handles both transfer and checking. A dedicated story stick costs little or nothing to make and is often the better choice when all the doors share one schedule of hinge positions.
Use a template when the hinge shape repeats
A hinge template helps locate the hinge outline and keeps the mortise boundaries consistent. Check its opening against the actual hinge leaf before marking. Even a small mismatch can leave the leaf proud or create a gap that shows after painting. Templates also need a firm, repeatable way to register against the jamb edge; a loose template can shift while you trace or score it.
For occasional work, a simple adjustable hinge marking template may be convenient, but inspect its stops and clamps before buying. A fixed template can be faster on a run of identical hinges, while an adjustable one is more adaptable but takes longer to set up. Neither replaces checking the hinge itself.
When the jamb is already installed, a full-size template may be awkward near a wall or trim. In that case, use the template to establish the hinge outline where it fits, then check the line with a square and mark the remaining edge by hand. Don’t force the tool against casing or a bowed jamb; a template that sits at an angle will transfer that error to every cut.
Mark the cut so the chisel has a clear boundary
Use a sharp pencil for rough reference marks, but score the final outline with a marking knife where a clean edge matters. A knife line severs the surface fibers and gives the chisel a boundary to register against. Keep the square pressed firmly to the jamb, and make light passes rather than trying to cut deeply in one stroke. On soft or painted wood, heavy pressure can drag the knife off line or lift the finish.
Mark the hinge depth from the leaf thickness, then verify it with a rule or depth gauge. Don’t assume every hinge leaf measures exactly the same. A mortise that is too shallow leaves the hinge proud, which can push the door out of alignment; one that is too deep can pull the door tight to the jamb and affect the reveal. Check the fit with the actual hinge before cutting all the gains.
For a simple depth check, a marking knife is more useful than a blunt pencil alone, though a pencil is perfectly adequate for general positions. If you already own a sharp utility knife, it can work for scoring; use a controlled, light cut and keep fingers clear of the blade.
Check the first cut before repeating it
Lay out and cut one hinge gain first. Set the hinge leaf into the recess and check that its face is flush with the jamb, the outline is neat, and the screw holes remain clear. If the fit is wrong, correct the reference or template before marking the remaining positions. Repeating a bad layout makes the repair larger, not easier.
Keep the chisel bevel oriented consistently and pare toward the scored boundary in shallow cuts. Chopping across the grain with too much force can split beyond the line, especially near the jamb edge. Leave the knife line intact until the waste is close to depth; then trim carefully. For repeated cut-outs, accuracy comes less from buying a complicated jig than from using one reliable datum, checking the first recess, and resisting the urge to rush the transfer.
