Step 1

Measure stair treads

Before ordering your new stair treads, it's crucial to determine the exact measurements. Don't worry, you can do it! Use our measurement sheet to note all dimensions in a structured way and easily transfer them to the configurator later.

1.1 Measure existing treads ("tracing")

→ Straight treads (rectangular)

Measure the width and depth of the tread. These dimensions already include the tread overhang (e.g., 900 × 280 mm).

→ Curved treads (non-rectangular)

Define zero point (P0): The absolute zero point (P0) is always the left corner at the front edge of the tread.
Measure corners clockwise: From P0, measure the x and y coordinates to each corner of the tread – always clockwise (P1, P2, …). Enter all coordinates in the measurement sheet.

1.2 Determine support surfaces without treads

→ Straight support surfaces

Measure the width and depth between the support brackets or walls.
Measure the length of the support surface as accurately as possible. The overhang (nosing) at the front edge will be added or adjusted in the configurator.

→ Irregular support surfaces

Also use the coordinate system. The zero point (P0) is at the left corner of the front edge of the support surface.
From there, measure the x/y coordinates of all corners clockwise – this clearly defines the dimensions.

If you're unsure about the coordinate system, use our short, easy-to-understand guide:

▸ Help: Understanding the coordinate system

When measuring your stair treads, we use a coordinate system to precisely determine the positions of the corners. It works as follows:

[Platzhalter: Diagramm des Koordinatensystems]

Imagine you're looking at the tread from above – we call this a top view.
Each tread has a front edge, and the starting point (P0) is the frontmost left corner of this edge. This is where you begin.
The x-axis runs from left to right, along the front edge of the tread.
The y-axis runs from front to back, into the depth of the tread.
Measure the x and y coordinates of each corner clockwise, starting at P0.

Calculate & adjust rise ratios

A consistent rise ratio is crucial for the safety and comfort of your staircase. To avoid confusion: A tread is the component you step on, while a rise describes the pure height difference. Here you'll learn how to calculate the ideal rise and professionally compensate for deviations.

Wichtig (DIN 18065)

The difference in rise heights between adjacent treads may not exceed 5 mm. The difference between the lowest and highest tread in the entire stair run may also not exceed 5 mm.

2.1 Calculate ideal rise height

Divide the total floor height by the number of rises to determine the ideal rise height.

Formel

Rise height = Floor height / Number of rises

Step rule: 2 × rise height (h) + tread depth (a) ≈ 60–65 cm.

→ Measuring the rise height

Measure the rise height from the horizontal support surface of the lower tread to the horizontal support surface of the tread above (90° vertical).

Alternatively: from top edge to top edge, if the alignment is correct.
Always take measurements at right angles to obtain precise values.

[Platzhalter: Skizze zur Messung der Steigungshöhe]

2.2 Adjust rise heights

If the existing rises are uneven, adjust them before installation.

→ Method 1: Adjustment with wood and shims

Place wooden strips or beams from the back edge to the front edge on the cleaned support surface (left and right, about 15 cm from the edge toward the center).
Align the supports exactly horizontally with shims; check with a spirit level.
Glue or screw the substructure.

[Platzhalter: Skizze zum Ausgleich mit Holz/Plättchen]

→ Method 2: Adjustment with screed or filler compound

Form the support surface and fill with screed or self-leveling filler compound.
After curing, sand the surface flat.

[Platzhalter: Skizze zum Ausgleich mit Estrich/Spachtelmasse]

Tips & Tricks

Smaller height corrections can also be achieved with different tread thicknesses. Example: A 2 cm tread with a 4 cm edge looks 4 cm thick and gains 2 cm in height. Important: Always glue thinner treads over the entire surface to prevent warping.

Note on substructure

If the stair structure is slanted or uneven, inclinations must be considered when measuring. Treads must not be slanted when installed – plan preparatory work for leveling if necessary.

Step 3 · optional

Determine risers

If you're planning a closed staircase with risers, you'll find the compact steps for the correct measurement here. For an open staircase without risers, you can skip this step.

3.1 Measure the rise height of each individual tread

→ Numbering of risers

Riser n refers to tread n above it. Riser 1 sits below tread 1, etc.

→ Measuring the rise height (vertical)

Measure the height for the riser at right angles (vertical) between the already leveled support surfaces of two treads on top of each other. This measurement should correspond to your calculated rise height.

Alternatively: measure from top edge to top edge, if the alignment is correct.
Always take measurements at right angles.

[Platzhalter: Skizze zur Messung der Setzstufenhöhe]

Hinweis

Details on tolerances (max. 5 mm difference) and measurement specifications can be found in Step 2.

If heights don't match

If individual rise heights deviate, adjust them as described in Step 2.2 (e.g., wooden strips/shims or screed/filler compound). Risers must not be slanted when installed.

Step 4

Manufacture or order treads

Once all measurements are final, it's time for implementation. Whether you have us manufacture the treads to fit or make them yourself – here are the most important tips for both approaches.

Pro tip: Order 1:1 paper templates first!

To avoid expensive measurement errors, we recommend ordering paper templates before final production. Place these 1:1 prints of your treads on the staircase and check if all dimensions and overhangs fit perfectly. This saves you time, money, and nerves.

[Platzhalter: Foto von Papierschablonen auf einer Treppe]

Order treads

Release production after template verification.
We manufacture to fit, with rounded edges and desired surface.

Make treads yourself

Glue template to wood and transfer contours.
Cut out treads, mill and sand edges.
Treat surface (oil or lacquer).

Step 5

Install wooden treads

Your treads are cut to size and surface-treated. Now it's time for fastening. Whether you glue or screw – clean preparation and the right technique ensure a stable and durable result.

5.1 Clean substrate

Remove dust and dirt from the support surfaces. A clean, load-bearing surface is the basis for durable installation.

5.2 Choose fastening method

Gluing (recommended): Apply assembly or parquet adhesive to the substructure. Place the tread and leave 1–3 mm distance to the walls (expansion joint). Gluing provides a clean look without screws and improves sound insulation.
Screwing: Pre-drill the treads. Place rubber or insulation strips between tread and substrate to prevent creaking noises. Use suitable screws with washers.

[Platzhalter: Skizze der Klebe- vs. Schraubmontage]

5.3 Check overhang

During installation, make sure the planned overhang at the front edge is even.

Wichtig

Thinner treads must always be glued over the entire surface to prevent warping.

Step 6

Aftercare and maintenance

To keep your new stair treads looking beautiful for a long time, proper care is crucial. Here are the most important tips to protect the surface and maximize the lifespan of your staircase.

6.1 Surface protection

Oiled: Re-oil regularly to maintain protection and appearance.
Lacquered: Sand and re-lacquer as needed.

6.2 Cleaning

Wipe with a slightly damp cloth. Avoid standing moisture.

6.3 Inspection

Occasionally check screwed treads for secure fit.

Glossary

Understand the technical language of stair planning. This glossary explains the most important terms so you have full clarity at every step.

Tread

Component of the staircase that is stepped on. Consists of the horizontal tread and optionally the vertical riser.

Rise (h)

Vertical height difference from one tread surface to the next. The number of rises is usually one more than the number of treads, as the last step onto the upper floor level is also a rise.

Tread depth (a)

Depth of the tread, the horizontal dimension from the front edge of one tread to the front edge of the next.

Floor height

Total height difference the staircase overcomes – from the finished floor below to the finished floor above.

Nosing / Tread overhang

Overhang of the tread over the tread or riser below. Increases the perceived tread surface and improves safety.

Standards and regulations (DIN 18065)

DIN 18065 defines the most important dimensions for stairs to ensure safety and comfort. Here's an overview of the key specifications you should consider in your planning.

Rise (h): 14–20 cm
Tread depth (a): 23–27 cm
Walking width: min. 80 cm (for ≤ 2 apartments)
Nosing: if tread depth ≤ 26 cm: a + u ≥ 26 cm
Tolerances: max. 5 mm deviation from nominal dimension (between adjacent treads and over the entire stair run)
Clear passage height: min. 200 cm

Conclusion

With exact measurements, careful planning, and clean installation, you'll create a staircase that is safe, comfortable, and aesthetically pleasing. Our 1:1 paper templates and configurator help you identify errors early and achieve perfect results.
