Rectangle Glasses Frames

Rectangle glasses frames are the foundation of the most popular eyewear style in the world — a shape defined by clean horizontal lines, a wide lens area, and proportions that flatter every face shape. Whether you’re shopping for your first pair of glasses or replacing a longtime favorite, rectangle frames are the most reliable choice you can make.

Types of Rectangle Glasses Frames

Full-rim rectangle frames completely surround the lens with frame material — the most durable and most visually striking option. Semi-rimless rectangle frames (half-frames) have a frame only along the top edge, with the bottom edge held by a thin nylon cord — lighter and subtler. Rimless rectangle glasses mount the lenses directly to the temples with no surrounding frame — the most minimal and lightweight option.

Rectangle Frame Materials

Acetate rectangle frames are made from a plant-derived plastic that’s durable, colorfast, and available in virtually unlimited colors and patterns. Metal rectangle frames — including stainless steel, titanium, and alloy — are thinner, lighter, and more adjustable. Combination frames use metal temples with acetate fronts for the best of both worlds.

Rectangle Frame Measurements

Rectangle glasses frames come in three key measurements: lens width (typically 48–58mm), bridge width (14–22mm), and temple length (135–150mm). Frame size is usually printed inside the temple as three numbers, e.g., 52-18-140. Wider faces should look for lens widths of 54mm or more; narrower faces suit 48–52mm lens widths.
