Lever Handle Size Chart: Length, Rose and Projection

Updated 2026-11-08 · RAYEN 雷茵

Three sizes decide whether a lever suits a door: how long it is, what it sits on, and how far it stands off the door. This chart covers all three across our lever handles. For door thickness and lock case, use the lever handle finder.

How long are lever handles?

On our drawings the overall length runs from the centre of the spindle to the tip of the lever. That is the reach a hand meets and the distance that has to clear a wall or a door stop.

• Shortest: SA-305 at 95mm, a rounded stainless lever.
• Most common: 125mm, 130mm and 135mm. More than a quarter of the levers that list a length sit on one of those three.
• Longest: KA5-916 at 168mm and KA5-2007 at 157mm.

The table starts with the shortest levers. Open any model to see its drawing.

What size roses do lever handles use?

• Round roses: Ø50mm on UL1005 and the KA82-9902 family; Ø52mm on most zinc alloy rose levers; Ø53mm on the stainless tube levers such as S-01; Ø54mm on the aluminium levers; up to Ø65mm on UL690.
• Square roses: 48 × 48mm to 55 × 55mm.
• Backplates: 185 × 45mm to 288 × 55mm, listed in lever handle plate sizes.

On a replacement, the new rose must be at least as large as the marks of the old one. An Ø50mm rose will not hide an Ø62mm footprint.

How far does a lever stand off the door?

Projection is the distance from the door face to the furthest point of the lever. Of the models that list it, the knob ET4017 sits closest at 50mm and UL1016 furthest at 80mm. The narrow-plate BK and ET levers sit at 52mm to 54mm; the stainless UL levers at 55mm to 80mm.

Projection matters in three places: a door that opens against a wall, a door that folds back against a cabinet, and a pair of doors where both levers meet in the middle.

Stainless levers with full dimensions

The UL and MUL stainless levers list lever length, drop and weight as well. Lever drop is a figure from the drawing; check what it measures on the model's own drawing before you rely on it.

On the same Ø50mm rose, UL745 weighs 0.38kg and UL1005 0.82kg. Weight follows the lever, not the rose.

How much room does a lever need?

Work it out on the door before you choose.

• From the lock: backset plus lever length is how far the tip reaches from the door edge. Check that against the hinge side of a pair of doors or a nearby wall.
• Behind the lever: projection plus a hand. On a door that opens against something, add the depth of the door stop.
• Below the lever: a long lever on a narrow stile can overhang a panel or glass. Check the drawing.

Lever length works with the lock: the backset of the case decides where the spindle sits. See lock case numbers.

What should you measure?

• Backset of the lock, door edge to spindle.
• The distance from the spindle to the nearest wall, frame or second leaf.
• The old rose or plate, if you are replacing one.
• Door thickness. See lever handle door thickness.

What to write on your order

Give the model, its length, the rose or plate, the lock case, the finish and the door thickness. For example: UL1005, lever length 130mm, Ø50mm rose, satin stainless, door thickness and lock case as measured. If two levers in a project must reach the same distance, write the length on both lines, not just the model.
