Choosing Door Handles for Thick, Thin and Rebated Doors
Door handles are not always a universal fit. The thickness and construction of the door can affect the spindle length, the way the handle is fixed and whether the supplied fittings will hold securely. Rebated doors, including many French doors and some pairs of external doors, need particular attention because the stepped meeting edges create an offset that standard hardware may not accommodate. Before choosing door handles, it is worth identifying the door construction rather than relying on appearance alone.
| Door Type | Typical Thickness/Construction | What to Check Before Buying |
|---|---|---|
| Standard solid internal doors | Commonly around 35–44 mm thick, with a solid timber, engineered or substantial core. | A normal spindle length will usually be suitable, but check the manufacturer’s stated door-thickness range if the door is unusually thick or has additional facings. |
| Thin or hollow-core doors | The overall door may be a conventional thickness, but the outer faces can be relatively thin with a lightweight or hollow internal structure. | Check whether bolt-through fixings are recommended and whether the supplied spindle can be adjusted or cut to the correct length. Poorly matched fixings or an unsuitable spindle can leave the handle feeling loose. |
| Rebated doors such as French doors | A pair of doors with stepped or overlapping meeting edges rather than two flat edges closing directly together. | Choose hardware specifically described as suitable for a rebated or offset arrangement. A standard setup may not position the spindle, lock furniture or associated fittings correctly across the stepped door construction. |
Measuring before you buy
Measure the door thickness at the exact point where the handle will be fitted, rather than measuring at the edge of a decorative panel, moulding or other raised section. The spindle passes through the lock or latch area, so this is the dimension that matters when checking whether the spindle supplied with a handle set is long enough. If the door is noticeably thicker than a typical internal door, compare your measurement with the fitting information for the handle before ordering from the all door handles range.
For a pair of doors, also check whether they are genuinely rebated. Open the doors and look at the meeting edges: a rebated pair has a visible step or overlap where one door closes partly over the other. This is common on French doors and on some paired front or external doors, but two doors meeting in the same opening are not automatically rebated. That distinction matters because hardware intended for a straightforward pair of square-edged doors may not suit the offset created by a rebate.
When comparing products, use the door type and compatibility information in the listing rather than trying to judge suitability from the product photograph. Lever handles can look virtually identical from the front while being supplied with different spindles, fixing packs or components for particular door arrangements. The product specification is therefore a more reliable guide than the visible shape or style of the handle.
Practical check before ordering: rebated doors and hollow-core doors are two of the most common causes of “wrong fit” enquiries. Confirm whether the door has a stepped rebate and whether its construction can take the supplied fixings before placing the order; those two checks resolve most compatibility problems before the handle reaches the door.
