Curtain poles versus curtain tracks
Choose for your curtain heading, the shape of your bay and how you want the curtains to move.
Choose a track for a discreet line
Gliders move inside a rail. A bendable track or supplier-bent system can follow a bay, but products differ in curtain load, bend radius and mounting options. Check the curtain heading and hooks; do not assume a track is suitable for eyelet curtains.
Choose a pole for a visible finish
A bay pole uses bends or corner connectors. Intermediate brackets can interrupt ordinary rings. If curtains must move across a support, choose a compatible passing-ring and passing-bracket system. Confirm the connector angle range and finial clearance with the supplier.
Think about the stack
Curtains need space when open. Check whether the fabric can stack clear of the glass, opening handles and the room entrance. Record any intended end returns separately and let the supplier confirm the final geometry.
When to ask for help
Heavy curtains, tight corners, uncertain fixing surfaces or a complex bow bay are good reasons to request a survey. Use the calculator as a brief for that conversation. It does not certify a product’s load capacity or fit.
