Cap Brim Shapes Guide: Flat, Curved, Wide and Short

A curved bill is the classic shape. It follows the head, reads tidy, and is the default for corporate, uniform and promotional headwear.

A flat bill keeps a straight line across the front. It reads streetwear or sport and is normally paired with a mid or high crown, because a flat bill on a low crown tends to look accidental rather than deliberate.

Width and length are separate decisions from curve. A wider, longer bill gives more shade and a stronger silhouette; a shorter bill keeps the cap compact and reads more casual.

Every bill is a sandwich: fabric on both faces with a stiffener between them. The stiffener decides whether the bill holds a curve, keeps a straight line, or takes a crease under compression.

Curved bills use a pre-formed insert that holds a set curve. Flat bills use a flatter insert or a heavier board so the line stays straight rather than curling.

Because the stiffener is inside, a bill cannot be judged from a photo alone. That is one reason we sample: the way a bill holds its shape is a physical property.

Flat bills are the most vulnerable to compression. Stacked without support, they crease, and a crease in the stiffener generally does not come out.

If your order ships individually to end customers, tell us at quotation. Brim-safe packing is simple to plan at production and awkward to add once the goods are made.

For mixed orders — some curved, some flat — separate cartons or divided packing keeps the flat bills from being pressed by the curved ones.
