How to measure basic walls before SUPAWOOD panel installation

Architectural projects can sometimes be difficult to measure when dealing with complex geometry, irregular shapes and forms, large surface areas, high ceilings, and buildings with difficult access.

In many architectural projects, precise measurement ensures that all products and systems fit together as intended. Measuring can be challenging when dealing with complex geometries like timber slat ceilings and large-scale projects specifying a system like timber acoustic panels.

Whether you use a tape measure or laser measuring equipment, the methods below will help you be more accurate in measuring walls and ceilings.

In the last blog, we went over the instructions and details around how to accurately measure ceilings before SUPAWOOD panel installation. These detailed instructions and examples are to ensure installation is as seamless and easy as possible onsite, ultimately avoiding untimely delays of the project. Here, we go over how to measure walls correctly, to prevent ill-fitting panels come time for installation.

In this blog, SUPAWOOD provides some valuable tips on how to measure walls and ceilings correctly, to prevent errors and incorrect ordering of panels. SUPAWOOD also wishes to express the importance of proper measurement for architectural lining systems. These detailed instructions and examples are provided to assist your installation onsite as seamlessly and easily as possible, ultimately avoiding untimely project delays.


Measuring Walls

Step 1:

Measure height at several spots e.g. A, B, C & D maximum 3600 Apart

1.1 - If floor does not yet have final covering, deduct thickness of covering (e.g. tiles / carpet) from height of wall.

1.2 - If height measurements vary by more than 15mm

1.2.1 - Mark a horizontal level datum line on the wall

1.2.2 - Measure up/down from datum line

Note: Some panels may need to be trimmed on site if the floor or ceiling vary from level by more than 10mm. 

Order panels at least 5mm longer than the maximum to make trimming easier. 

Note you can also order rectangular panels that step by 2mm at a time, which will not be obvious but will give you a consistent joint line to the floor or ceiling.

Step 2:

When Supawood panels are bordered on both sides by 90° corners to other surfaces, measure width like this:

Measure width of area at top, bottom & centre, (or at 2400mm intervals if over 4m high wall) e.g. E, F & G.

2.1 - If adjoining walls do not yet have final lining deduct (if internal corner) or add (if external corner) thickness of lining from measurement.

2.1.1 - If plasterboard, allow plasterboard thickness + 2mm for setting.

2.1.2 - If Supawood, allow for any framing still required as well as panel & battens.


2.2 - If width measurements vary by more than 8mm.

2.2.1 - Put a long spirit level against each of the adjoining walls.

2.2.2 - Identify which wall/walls are out of plumb by more than 5mm.

2.2.3 - Measure how much wall is out of plumb at top, bottom & middle. e.g.

2.2.4 - Note: Some panels may need to be trimmed on site if any adjoining surface is more than 8mm out of plumb.

2.2.5 - Sometimes the adjoining surface can be packed out / adjusted to plumb.


Step 3:

When one or more vertical perimeters of the lined area are angled external or internal corners, or the lined area is curved or faceted, use this procedure:

3.1- Mark on floor the line of the face of the panel

3.1.1 - Allow for:

  • panel
  • fixing batten
  • framing not yet installed

3.1.2 - A 'jig' of the required thickness can make this quicker.


3.2 - Mark on floor the finished lining face of any adjoining surfaces not yet fully lined.  Allow for setting on plasterboard (2mm extra)


3.3 - Mark both edges of each panel on the floor.

3.3.1 - Use Supawood Joint Details drawings to determine exact offsets at each type of junction.

3.3.2 - Mark both sides of each express joint (where applicable)

3.3.3 - Use vertical laser to transfer overhead points to floor from ceiling if required.


3.4 - Measure each panel width on floor.

3.4.1 - Use tape measure.

3.4.2 - Use vertical laser or similar, to measure horizontal distances down steps, or for shaped wall panels, E.g.

3.5 - Check measure overall distance.

3.5.1 - Measure from LHS of left-hand panel to RHS of right-hand panel.

3.5.2 - Compare measurement to total of all the panels and all express joints, must be within 1mm (E10) or 1/2mm (B3)/per metre.

3.5.3 - Recheck individual panel measurements as required.
