Choosing the right size is the most common question before buying a medical plus or pharmacy LED board. Signs and Arts boards come in two main sizes — 18″×18″ (about 45×45 cm) and 24″×24″ (about 60×60 cm). The right one depends on how far away customers see your shop and how much wall space you have.

How to choose your size in 30 seconds
Stand where your customers usually stand — the bus stop, the opposite footpath, or the road. If that distance is roughly the width of a normal road or less, 18″×18″ is enough. If your shop is set back, on a first floor, or on a wide highway, go for 24″×24″ so the plus symbol stays clearly readable.
Does size change brightness or features?
No. Both sizes use the same ultra-bright pixel LEDs, the same weatherproof iron frame, double-sided display and plug-and-play 230V power. The larger size simply has a bigger lit area and more LEDs, so it reads from farther away. Both are equally suitable for outdoor use — see our outdoor waterproof guide.
