4×8 or 5×10: the right ACP panel format.
The Ahlum aluminum composite panel comes in two standard formats. For the professional buyer — architect, contractor, sign shop, distributor — the right choice depends on the surface to cover and the number of seams you can accept, not just the price per panel. This guide covers the dimensions and the selection criteria between 4×8 and 5×10.
4×8, 5×10:
what they measure.
Two formats, one construction: two 0.5 mm 5005 aluminum skins on a polyethylene core, matte PVDF finish, 4 mm total thickness. Only the panel surface changes.
| Format | Dimensions |
|---|---|
| 4×8 | 1220 × 2440 mm (48″ × 96″), 32 sq. ft. per panel. The standard North American format, for most projects. |
| 5×10 | 50 sq. ft. per panel. Reduces the number of seams on a large surface — reserved for distributor accounts. |
How to choose
between 4×8 and 5×10.
Three questions to settle before specifying a format in a quote or an order.
Surface & seams
4×8 fits most projects. 5×10 reduces the number of seams on a large commercial façade or a full-height sign.
Distributor account
5×10 is reserved for distributor accounts. 4×8 is available per unit or in volume.
Handling & transport
A larger format needs more handling space on site. See the detail of the construction and the panel's PE core.

your questions.
What is the difference between the 4×8 and 5×10 format?
4×8 (1220 × 2440 mm, 48″ × 96″, 32 sq. ft.) is the standard North American format, suited to most projects. 5×10 (50 sq. ft.) reduces the number of seams on a large façade or a full-height sign, but is reserved for distributor accounts.
Is the 5×10 format available per unit?
No. The 5×10 format is reserved for distributor accounts — see the distributor program and volume pricing.
Does the panel composition change with the format?
No. Both formats share the same construction: two 0.5 mm 5005 aluminum skins on a polyethylene core, matte PVDF finish. Only the panel surface changes.
