High-speed doors made to measure: common sizes

High-speed doors are made to measure in almost any width and height. Common sizes range from 2 × 2 m to 5 × 5 m, and special sizes are also possible. Here you will find the typical sizes with opening area, use and space requirements.

High-speed door sizes at a glance

The table shows the most common high-speed door sizes with opening area and typical use. Each size refers to the clear width × height of the door opening.

Size (W × H)	In mm	Opening area	Typical use
2 × 2 m	2,000 × 2,000	4 m²	Internal passages in production and warehousing, transitions to cold and clean areas, material locks, routes for automated guided vehicles
3 × 3 m	3,000 × 3,000	9 m²	Logistics and warehousing, production, goods-in, transitions between hall areas, outdoor doors at secondary entrances
3 × 4 m	3,000 × 4,000	12 m²	High-bay warehouses, goods-in with tall load carriers, passages for reach trucks, production with tall components
4 × 4 m	4,000 × 4,000	16 m²	Hall passages with two-way traffic, workshops and vehicle fleets, outdoor doors at secondary entrances, production with large components, distribution lorries with low bodies
4 × 5 m	4,000 × 5,000	20 m²	Lorry passages and indoor loading, commercial vehicle workshops, heavy-load and special logistics, mechanical engineering with tall components, vehicle halls
5 × 5 m	5,000 × 5,000	25 m²	Main entrances to industrial and logistics halls, lorry passages with turning in, construction and agricultural machinery, large parts in machine and plant engineering, vehicle halls

Which size for which traffic?

The guide values below assume the usual safety margins to both sides and above the vehicle or load:

• 2 × 2 m: for narrow, busy passages with pedestrians, pallet trucks, narrow tugger trains and low industrial trucks; vehicles and loads up to approx. 1,000 mm wide and 1,700–1,800 mm high.
• 3 × 3 m: the most common standard size for halls, covering normal forklift and tugger train traffic and feasible in almost every design; up to approx. 2,000 mm wide and 2,700–2,800 mm high.
• 3 × 4 m: the upright format for tall loads or high masts where the vehicle width stays below about 2 m; up to approx. 2,000 mm wide and 3,700–3,800 mm high.
• 4 × 4 m: for wide hall passages with two-way traffic, large equipment and vans; up to approx. 3,000 mm wide and 3,700–3,800 mm high – too low for lorries at the full height of 4 m.
• 4 × 5 m: the smallest standard size through which lorries up to 4 m high can enter with a safety margin; up to approx. 3,000 mm wide and 4,700–4,800 mm high.
• 5 × 5 m: for main entrances to large halls where lorries turn in at an angle, vehicles meet or bulky goods are moved; up to approx. 4,000 mm wide and 4,700–4,800 mm high.

How to find the right size

The right size is determined by the largest vehicle, including its load, that will pass through the opening, plus a safety margin on both sides and above. For forklift trucks, the height of the mast or of the highest load counts; for lorries, the vehicle height including the body. An opening that is too tight leads to impact damage to the curtain, while one that is too large wastes energy and time with every opening cycle.

For the first enquiry, the clear width and height of the opening are sufficient. For detailed planning, the space above and beside the opening is added – see the guide values in the next section. Before manufacturing, all dimensions are agreed bindingly with you or your installer.

Headroom and side room: guide values

Besides the clear opening, two further dimensions are decisive: the headroom above the opening for the winding shaft or spiral guide and the drive, and the side room to the left and right for the side guides. The drive side usually needs more space. The values are guide values and vary with design, curtain and wind locking.

If space is limited, space-saving designs, a laterally arranged drive or mounting in front of the wall opening come into question. When mounted in the reveal, the clear passage is reduced by the width of the frames.

Size	Typical headroom	Typical side room per side	Drive side
2 × 2 m	approx. 400–600 mm	approx. 150–250 mm	approx. 300–400 mm
3 × 3 m	approx. 450–650 mm	approx. 150–250 mm	approx. 300–450 mm
3 × 4 m	approx. 500–700 mm	approx. 200–300 mm	approx. 300–450 mm
4 × 4 m	approx. 550–750 mm	approx. 200–300 mm	approx. 350–500 mm
4 × 5 m	approx. 600–850 mm	approx. 200–350 mm	approx. 350–500 mm
5 × 5 m	approx. 650–900 mm	approx. 250–350 mm	approx. 400–550 mm

Small and large high-speed doors

Small doors up to about 2.5 m wide separate passages for pedestrians, pallet trucks or tugger trains and, thanks to their low curtain weight, reach particularly high speeds. Large doors from around 4 × 4 m are used in external walls, loading areas and vehicle halls; here, wind load, curtain stability and drive power come to the fore. For outdoor doors, the wind resistance class according to EN 12424 is defined for the specific location, usually with a reserve for exposed façades.

For very large or heavily wind-loaded openings, a fold-up door is an option, typically from approx. 3,000 × 3,000 mm up to approx. 10,000 × 8,000 mm depending on the system. At the other end of the scale, clear curtain doors and indoor high-speed doors are the typical choice for compact passages with very high cycle rates.

Special sizes

High-speed doors are always made to measure – the sizes above are guide values, not fixed steps. In the configurator you set width and height from 1,000 to 5,000 mm in 50 mm steps. Larger openings are marked as a special size and checked individually, because above a certain size the design, wind resistance class and drive have to be reassessed.
