Curtain rod guides
Curtain rod diameter: 20, 25 or 30 mm
Tube diameter sets both load capacity and visual proportion. The longer the rod and the heavier the curtain, the thicker the tube you need.
20 mm — light and refined
A slim, elegant tube for light and medium curtains over short-to-medium spans. Good for bedrooms and kitchens where the fabric is not heavy.
25 mm — the all-rounder
The sweet spot: holds medium and heavy curtains and looks right in both living rooms and bedrooms. The safe choice for most windows.
30 mm — for long, heavy curtains
A thick tube for large windows and heavy, dense fabric. It reduces sag on long rods and suits a more massive interior.
FAQ
Which diameter is most universal?
25 mm — it holds medium and heavy curtains and fits most rooms. When in doubt, pick 25 mm.
What diameter for a long window?
For wide windows and heavy curtains, 30 mm is better — it sags less and is sturdier.
