“Small” and “standard” are not fixed catalog names. On a real project the difference is the leaf width, the swing arc the leaf sweeps, and how much clear floor you must keep free. A small swing door is built for tight passages; a standard swing door is built for normal room-to-room or entry traffic. Same hinge principle, very different planning.
Industry size references — not ALPES catalog numbers, so confirm the exact system with ALPES — place a small or narrow passage leaf at roughly 12–24 in (300–600 mm) wide, a standard single leaf at about 28–36 in (710–915 mm), and a standard double swing door at a combined 48–72 in (1220–1830 mm) across two leaves. Heights run 80–96 in (2030–2440 mm) on both. The takeaway is simple: “small vs standard” is a width question first, and everything else follows from that width.
| Attribute | Small swing door | Standard swing door |
|---|---|---|
| Leaf width | 12–24 in (300–600 mm) | 28–36 in single / 48–72 in double |
| Swing arc radius | Small, about half a standard leaf | Larger, needs more clear floor |
| Typical use | Pantry, powder room, utility, closet | Room divider, entry, balcony, villa |
| Glazing | Often solid or a small lite | Often a full or large glazed leaf |
| Hardware load | Light leaf, simple hinges | Heavier glazed leaf, tested hinges/locks |
| Code note | Still needs clear opening where egress applies | ADA 32 in clear where accessibility applies |
A swing door does not just need the opening; it needs the floor the leaf sweeps. A 36 in standard leaf swings through roughly an 18 in radius arc on each open — that is floor you cannot furniture-block. An 18 in small leaf needs about half that. In a powder room or galley kitchen that difference is the line between a workable plan and a door that hits the vanity. Plan the arc, not just the rough opening.
The leaf size does not change the aluminum system underneath. Across its catalog ALPES builds on 6060-T66 alloy at 1.8–2.5 mm wall, with PA66GF25 multi-chamber thermal break and German hardware (ROTO, Winkhaus, CMECH, Wehag). Those same materials carry into a swing door whether the leaf is small or standard. What you must confirm per project is swing-door-specific: the exact leaf dimensions, the tested thermal value for the glazed leaf, and the hinge and lock rating for the leaf weight. Do not assume a casement-window K-value applies to a swing door — ask for the system’s own certificate.
Swing doors are handed: left-hand or right-hand, depending on which jamb the hinges sit on and which way the leaf opens. Standard glazed leaves are heavier, so hinge load rating and a tested lockset matter more than on a light small leaf. For villas in coastal or hot climates — Saudi Arabia, Dubai, and Australia are all ALPES project markets — specify stainless or coated hinge hardware and a multi-point lock sized to the leaf, and confirm the finish. Standard powder-coat colors are Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee, with custom dual-color matching available.
| If your opening is… | Choose | Why |
|---|---|---|
| 12–24 in tight passage | Small swing door | Fits where a standard leaf and its swing arc will not |
| 28–36 in normal room or entry | Standard single | Comfortable passage, furniture-friendly |
| 48–72 in entertaining opening | Double swing door | Symmetrical wide clear width |
| Wheelchair / ADA 32 in clear needed | Standard (min 32 in clear) | A small leaf usually fails egress |
| Hot or coastal climate, glazed leaf | Thermal-break aluminum, tested hardware | PA66GF25 plus German hardware |
| Ask the supplier | A good answer looks like | Red flag |
|---|---|---|
| Leaf width schedule per opening | Exact mm per leaf, rough-opening allowance | “Standard size” with no numbers |
| Hardware brand and test cycles | ROTO / Winkhaus / CMECH named, cycle count | Unnamed “imported” hardware |
| Thermal certificate for the leaf | System’s own K or U value, lab report | Borrowing a window’s number |
| Finish standard | Powder-coat spec, color codes | Vague “painted” |
| Delivery format | FCL from 100,000 m² Foshan / Zhaoqing base | Vague lead time |
Small or standard, the door is only as good as the system behind it. ALPES builds aluminum swing solutions on the same 6060-T66 plus PA66GF25 plus German-hardware baseline used across its villa projects in the Middle East and Australia, direct from a 100,000 m² Foshan and Zhaoqing base.
