How Many Acoustic Panels Do I Need?

The sum is simple, and our online panel designer does it for you in millimetres, centimetres or feet and inches.

Premium acoustic panels drawn by our online panel designer

The sum

Our acoustic panels are 600 mm wide. Divide the width of your wall by 600 and round up: we sell whole panels only, never half panels. Each panel is then cut to the height you need, up to 2400 mm.

So a wall 3 m (3000 mm) wide takes 3000 ÷ 600 = 5 panels. A wall 3.2 m wide takes 6, with the last one trimmed to fit when it goes up.

Wall widthPanelsPremium panels, including VAT
1.8 m3 panels£540
2.4 m4 panels£720
3.0 m5 panels£900
3.6 m6 panels£1,080
4.2 m7 panels£1,260
4.8 m8 panels£1,440

Measuring in feet and inches?

A 600 mm panel is just under 2 feet wide (about 1 ft 11⅝ in). A 10 ft wall is 3048 mm, so it takes 6 panels. Our online designer takes feet and inches, centimetres or millimetres and answers in the same units.

What about the height?

Each premium panel is cut to any length up to 2400 mm, at the same price, with the slats running up. For a wall taller than 2400 mm, talk to us: our team can fit panels with a filler strip to the ceiling.

What it costs

  • Premium panel: £180 each including VAT, in black or white felt with slats in any Egger or Swiss Krono décor.
  • Fixing kit: £10 a panel.
  • LED light kit: £150 for one light up to £290 for six. Each light is a 2.4 m warm-to-cool-white strip that sits in a gap between the slats, dimmable with a remote.
  • Delivery: £25, free from 5 panels; or collect from our Livingston showroom.

Would you rather we fitted them? Fitted panels are £125 (standard) and £250 (premium) each: see Acoustic Wall Panels.

Let the designer do the sum

Our online panel designer asks for your wall's width and height, tells you how many panels you need, and draws them on your wall in the felt and slat colour you choose. More: acoustic wall panels · acoustic panels for media walls

Common questions

Five. Acoustic slat panels are 600 mm wide, and 3000 ÷ 600 = 5. For any wall, divide its width in millimetres by 600 and round up to a whole panel.
