Acoustic panel calculator
Calculate acoustic panels and adhesive for a wall from your measurements.
Acoustic panel calculator
Calculate the number of acoustic panels and adhesive for a wall based on your measurements and panel size.
Width of the wall you want to cover
Height of the covered area
Acoustic panels are typically 600 mm wide
Pick the panel length you buy
Allowance for cuts at edges, sockets and corners
Your acoustic panel project
8 acoustic panels for 9.6 m² wall
Area
11.52 m²
Panels
8 pcs
Materials
For 9.6 m² wall
About 1 tube per 1.5–2 m² of panel
ℹThe result is an estimate based on your dimensions, panel size and waste.
ℹAdhesive consumption is indicative – always follow the manufacturer's instructions on the tube.
Example: a 4 × 2.4 m wall
A 4 × 2.4 m wall is 9.6 m². With 600 mm wide full-height panels you'll need 7 panels plus a little waste – and about 6 tubes of adhesive.
Calculation for a 4 × 2.4 m living-room wall with 600 × 2400 mm panels:
Pick a panel height ≥ your wall height to avoid horizontal joins across the middle of the wall.
How to calculate acoustic panels
Always measure the full surface
Acoustic panels are typically 600 mm wide and 2400, 2440 or 3000 mm tall. The calculator places panels side by side across the wall width, so the count comes from wall length divided by panel width. Choose a panel height that is at least your wall height to avoid ugly horizontal joins.
Don't rip felt-backed slats lengthways
Most acoustic panels are wooden slats on an acoustic felt backing. You can cut the felt between slats, but a slat ripped lengthways rarely looks good. Plan the layout so full panels stay visible and any cuts end up in a corner or behind furniture.
Adhesive or screws?
The easiest method is mounting adhesive straight onto a flat, solid wall (drywall or plaster). Plan for about 1 tube per 1.5–2 m². On uneven walls, or if you want to be able to remove the panels, screw them to vertical battens every 40–60 cm – that needs extra timber and screws.
Waste and sockets
Add 10 % for cuts at the ceiling, floor, sockets and corners. If you have lots of cut-outs for sockets, lights or radiators, plan for 15 % instead.
How to use this calculator
Four quick steps – you don't need to be a tradesperson to follow them.
- Measure the wall length and the height of the area you want to cover.
- Pick a panel width (typically 600 mm) and a panel height that's at least your wall height.
- Add 10 % for waste to cover cuts at edges, sockets and corners.
- Tick the adhesive option so the tube count lands on your shopping list.
Common mistakes
Small things that often cost an extra trip to the hardware store.
- Choosing a panel height lower than the wall – you end up with an ugly horizontal join across the middle.
- Ripping an edge slat lengthways instead of planning the layout so cuts land in a corner.
- Forgetting adhesive or battens – panels need a flat, solid surface to fix to.
- Not checking for hidden cables and pipes before drilling or gluing.
Example: a 4 × 2.4 m living-room wall
A 4 × 2.4 m wall is 9.6 m². With 600 mm wide panels at 2400 mm tall you need 7 panels across – the panel covers the full height, so that's 1 row. With 10 % waste that's 8 panels, plus about 6 tubes of adhesive.
Frequently asked questions
Short answers to the questions we hear most often about this calculator.
How wide are acoustic panels usually?
Most are 600 mm wide (some 580 mm) and come in 2400, 2440, 2750 or 3000 mm heights. Pick a height that covers your wall in one piece.
Should I use adhesive or screws?
On a flat, solid wall, adhesive is easiest – plan for about 1 tube per 1.5–2 m². On uneven walls, or if the panels need to come down again, screw them to vertical battens every 40–60 cm.
How much waste should I add?
10 % is fine for a normal wall. With lots of sockets, windows or angled corners, plan for 15 %.
Can I fit acoustic panels in a bathroom?
Wooden slats don't suit wet rooms or direct moisture. Use them in living rooms, offices, bedrooms and home cinemas – not inside shower areas.
