Aluminium Sign Sizes: From A4 Door Signs to 60×40in Site Boards

From compact door signs to large aluminium sign boards, size should follow how far away people will be when they need to read the sign, not just how much wall is free. The uses below are a starting point, not a rule.

Unsure between two sizes? Tape a full-size paper version where the sign will go before ordering.

3mm Aluminium Composite for Durable Outdoor Signs

Aluminium composite (ACM) pairs two thin aluminium skins with a solid core. That gives you a sign that's rigid and flat like metal but far lighter than solid aluminium sheet, so it's easier to handle, fix and transport. For a business sign that has to stay up, that matters: aluminium doesn't rust the way steel does, and the panel resists the swelling and warping that can affect paper-based or foam boards left outdoors. As with any outdoor print, how long the printed face stays vivid depends on sun exposure, location and care.

You'll see similar material sold under trade names such as Dibond. We list ours by its specification, 3mm aluminium composite, so you know exactly what you're buying.

Square or Rounded Corner Aluminium Composite Signs

CAD cut square corners give a sharp, architectural edge that suits modern shopfronts, office walls and industrial units. CAD cut radius corners are rounded, which softens the look and is often preferred where people pass close by or might brush against the sign, such as corridors, schools, clinics and waiting areas.

Drilled or Undrilled Aluminium Signs

Drilled aluminium signs are ready to screw straight onto walls, fences, gates and hoardings. Choose no drilling if you'll use adhesive pads, a frame, a post system or your own fixing method. If you choose drilled, keep important text and logos clear of the corners so the screw heads don't cut into them.

Custom Aluminium Signs for Businesses, Shops and Outdoor Sites

Aluminium shop signs and business entrance signs. Name boards, opening hours and entrance signs that need to look as professional in year three as they did on day one. Where the sign goes matters as much as the sign itself, which is why we've written about choosing the right location before you drill.

Construction and site signs. Site rules, contractor branding and safety information on fences and hoardings, where a rigid board fixes cleanly to temporary structures and stays readable through rain, wind and site dust.

Property and development signs. Estate agent signs, development boards and "now letting" panels that need a polished finish on show homes and commercial premises.

Directional and wayfinding signs. Car park directions, business park signage and information boards that guide visitors from the entrance to the right door.

Offices, schools and clinics. Aluminium office signs and indoor information panels, often with radius corners.

Aluminium Composite Signs vs Other Sign Materials

Aluminium composite isn't the answer to every signage job. Here's an honest comparison across our signage range.

Artwork Requirements for Aluminium Composite Sign Printing

Most reprints come from artwork problems rather than print faults: a phone number with a missing digit, a logo too close to the edge, low-resolution images that looked fine on a screen. Building your file to these specifications avoids most of them:

• Format: PDF
• Bleed: 3mm all round
• Safe zone: 3mm (keep all text and logos inside it)
• Resolution: 300dpi minimum
• Colour: CMYK
• Fonts: outlined or embedded

A sign built to last years should carry information that stays true for years, so keep prices and short-term offers off the panel. Our guide to designing signs that stay right for as long as they last explains how. If you'd rather not build the artwork yourself, our design team can create it around your logo, colours and fonts.

Aluminium Composite Signs: Questions Before You Order

What sizes of aluminium composite signs can I order?

You can order aluminium composite signs in A4, A3, A2, A1 and A0, plus 20×30in, 40×30in and 60×40in. Every size is 3mm aluminium composite, printed single-sided, with square or radius corners and an optional drilled finish. Choose the size to suit how far away the sign will be read.

How much do aluminium composite signs cost?

The price depends on size, quantity, number of sets, finishing and production speed. It updates live as you configure the product on this page and is shown plus VAT, so you can compare options, such as A1 against A0 or standard against express production, before adding anything to your basket.

Are aluminium composite signs suitable for outdoor use?

Yes. Aluminium composite is designed for long-term outdoor signage. Its aluminium skins don't rust, and the rigid panel resists the warping and swelling that affect lighter boards. As with any printed sign, how long the print stays vivid depends on sun exposure and location.

What's the difference between ACM signs and aluminium composite signs?

There's no difference. ACM stands for aluminium composite material, so ACM signs, custom printed ACM panels and aluminium composite signs all describe the same product. Ours are 3mm aluminium composite, printed single-sided and cut with square or radius corners.

Can I order aluminium signs with drilled holes?

Yes. Choose the drilled finishing option and your signs arrive ready to screw to walls, fences, gates or hoardings. If you plan to use adhesive, a frame or a post system, choose no drilling instead.

Are your aluminium composite signs double-sided?

No. Our aluminium composite signs are printed single-sided, which suits signs fixed flat to a wall, fence or gate. For a sign read from both sides, such as a projecting sign, a two-sided format is a better choice.

How quickly can I get printed aluminium signs?

Choose express, 1 working day or 3–4 working days production when you order. Because printing needs your final artwork, uploading your print-ready PDF at checkout rather than sending it later is the quickest route to dispatch.

Can you design my sign for me?

Yes. If you don't have print-ready artwork, our design team can create your sign around your logo, brand colours and message. Otherwise, choose "Send It Later" at checkout and supply your PDF using the link we provide.

Ready to Order Your Aluminium Composite Signs?

Choose your size, corners and finishing, upload your PDF or send it later, and add your aluminium composite signage to the basket. You'll see the price before you commit. For a sign that's meant to stay up, it's worth getting the panel right the first time.
