Pinus quadrifolia is a small to medium size tree, reaching 8 metres to 15 metres tall and with a trunk diameter of up to 40 centimetres , rarely more. The bark is thick, rough and scaly. The leaves are in fascicles of 4–5, moderately stout, 2.5 centimetres - 5.5 centimetres long; glossy dark green with no stomata on the outer face, and a dense bright white band of stomata on the inner surfaces. The cones are globose, 4 centimetres - 5.5 centimetres long and broad when closed, green at first, ripening yellow to orange-buff when 18–20 months old, with only a small number of thick scales, with typically 5–10 fertile scales.
