Matte business cards have a smooth, low-glare finish that is easy to read under bright light. They suit understated designs, soft colours, and cards that may need to be written on, although writing performance depends on the exact stock and coating.
Glossy cards have a shinier surface that can make photographs and strong colours appear more vivid. The coated surface is less suitable for handwriting. Check the product specifications for the stock, coating, and available print-side options before ordering.
