Body copy

Signage is the highest-ticket category in printing and branding, and the one where price variation is widest. A small ACP sign and a set of illuminated 3D channel letters differ by an order of magnitude, and the right choice depends on your location, budget and how long you need the sign to last.

This guide sets out what signage costs in Nairobi in 2026, the differences between the main sign types, and what to specify when you order.

ACP vs acrylic vs 3D letters vs channel letters

ACP (Aluminium Composite Panel) is the workhorse of shop signage. It is flat, durable, weatherproof and relatively inexpensive. ACP signs cost KSh 3,000 to KSh 8,000 per square metre and are the standard choice for shop fronts and building signs.

Acrylic signs are solid plastic, often used indoors for reception areas and office branding. They look more premium than ACP and cost KSh 5,000 to KSh 15,000 depending on size and thickness.

3D acrylic letters are individual cut letters, often mounted on a wall or shop front. They cost KSh 800 to KSh 2,500 per letter depending on size and thickness. A business name of eight letters typically runs KSh 10,000 to KSh 20,000.

Channel letters are illuminated 3D letters, usually with LED modules inside. They are the premium outdoor option and cost KSh 1,500 to KSh 4,000 per letter. They are visible day and night and are the standard for professional shop fronts.

LED signs are full digital displays, suitable for high-visibility outdoor locations. They start at KSh 15,000 and can exceed KSh 50,000 for large installations.

Lightbox signs are illuminated panels, typically used for 24-hour visibility. They cost KSh 8,000 to KSh 25,000 depending on size.

What affects the price

Size is the primary driver. Signage is usually priced per square metre or per letter, so the total cost scales directly with the physical dimensions.

Illumination adds significantly. A flat ACP sign and an illuminated channel letter sign of the same size can differ by a factor of three or four. LED modules, transformers and wiring all add cost.

Installation complexity matters. A sign mounted at ground level is cheap to install. A sign mounted at height on a building facade requires scaffolding, cranes and safety equipment, which can double the installation cost.

Material thickness and quality. Acrylic is available in 3mm, 5mm, 8mm and 10mm. Thicker material costs more but looks more substantial and lasts longer.

How long does signage take?

ACP and acrylic signs typically take 3–5 working days including fabrication. Illuminated signage (channel letters, LED, lightbox) can take 5–10 working days due to electrical components and testing. Large pylon and monument signs can take several weeks.
