For GT2 belts, circumference = number of teeth × 2mm. For example, a 50-tooth belt has a 100mm (≈3.94\") circumference. Most desktop 3D printer extruder drives typically use belts in the 88–102mm range.

They are designed to fit pulleys commonly used in Creality Ender 3, Ender 5, CR-10, Prusa-style extruders, and most open-frame CNC routers that use GT2 drive systems.

Most desktop 3D printers — including Ender 3, CR-10, and similar machines — use 6mm wide GT2 belts on their extruder and axis drives. The 10mm wide variant is typically used in heavier-duty CNC routers or custom builds where the wider belt provides additional torque capacity.

This eliminates the weak point present in joined belts and ensures consistent tension and smooth power transfer throughout the belt's life. Open-end belts are cut to length and require a tensioner or clamp to secure the ends. Closed loop belts are the correct choice for fixed-distance pulley setups such as 3D printer extruder drives where the pulley spacing does not change.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I count teeth to confirm I'm ordering the correct belt size?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eFor any GT2 belt, tooth count = circumference ÷ 2mm pitch.
