Choose the 2-door locker if each person needs to store long clothing unfolded, such as work overalls or a coat: each door opens onto a compartment that runs the full height. If what gets stored is a rucksack, a jacket and a pair of shoes, the 4-door locker serves twice as many people in the same 65 cm width, with compartments 82 cm high.
The 6- and 12-door lockers follow the same logic at 97 cm wide. The 6-door repeats the 82 cm compartment of the 4-door; the 12-door splits it into 41 cm compartments, which are no longer meant for clothes. All four are 177 cm high and 40 cm deep, so they line up in the same row.
What fits behind each door?
| Locker | Compartment (height × width) | What fits | People per metre of wall |
|---|---|---|---|
| 2 doors, 177 × 65 cm | Full height × 28 cm | Overalls or coat unfolded, shoes below | 3 |
| 4 doors, 177 × 65 cm | 82 × 28 cm | Rucksack, jacket, shoes | 6 |
| 6 doors, 177 × 97 cm | 82 × 28 cm | Same as the 4-door, spread over three columns | 6 |
| 12 doors, 177 × 97 cm | 41 × 28 cm | Cycle helmet, small bag, charger, light PPE | 12 |
The last column is simple arithmetic: doors divided by width in metres, rounded down. What people forget when measuring is the opening. The door is 28 cm wide on every model, and 157 cm high on the 2-door, 78 cm on the 4- and 6-door and 40 cm on the 12-door. Anything that won't pass through there won't go in, however much room there is inside.
Watch out for "4 doors", because the TwinThink range has two. The one in the table has two columns and 82 cm compartments. The other is a single column 33 cm wide and 165 cm high, with no legs and four small 41 cm compartments. It is the narrowest locker we sell, it fits between two pillars where nothing else will, and per metre of wall it gives as many doors as the 12-door. It is no good for long clothing.
When is the 2-door worth it?
When clothes need to go in full length, unfolded. It is the locker for the changing room of a factory, a workshop or a kitchen, where people arrive in their own clothes and put on overalls or a uniform. You pay for it in wall space: three people per metre, half as many as the 4-door. That is why a large changing room usually works out better mixed, with 2 doors for those who change completely and 4 for those who only drop off a rucksack.
If your staff change for work, regulation 23 of the Workplace (Health, Safety and Welfare) Regulations 1992 requires "suitable and sufficient accommodation" for the clothing people do not wear during working hours, and paragraph (2)(a) adds suitable security for it where changing facilities are required. It gives no dimensions. What counts as sufficient depends on what is stored, and for overalls or a uniform kept unfolded, the full-height compartment is the one that does the job. What the regulations ask for, point by point, is in our guide to changing-room lockers under the Workplace Regulations. This is general guidance, not legal advice.
4-door or 6-door?
Both work when each person leaves a rucksack and a jacket, which is the usual case in offices, schools, gyms and staff rooms. The 82 × 28 cm compartment has a removable shelf, with room for that and for shoes. A long coat will have to be folded.
The compartment is the same and so is the density, six people per metre. What changes is the width, 65 cm against 97 cm, and that decides which one makes better use of your wall:
- In a 1 m gap, one 6-door locker holds the belongings of 6 people. A 4-door stops at 4 and leaves 35 cm empty.
- In 1.30 m, two 4-door lockers fit, 8 compartments. A 6-door stops at 6 and leaves 33 cm to spare.
- Along a 1.95 m stretch it makes no difference: three 4-door or two 6-door lockers both give 12 compartments.
If your wall measures something else, the locker calculator gives you the number of lockers and metres of wall from how many people use the changing room at the same time and what they store.
What is the 12-door for?
For belongings. The helmet and gloves of someone who cycles to the office, or a phone and wallet at a sports centre. It fits twelve people per metre of wall, twice the 4-door. A coat won't go into 41 cm, and it is better to say so before someone tries.
And at home?
At home you count by family, not by headcount. In the hallway, a 4-door locker gives each member of a family of four their own 82 cm compartment for a school bag, a jacket and shoes. The 12-door makes more sense in the garage, with cycle helmets, gloves and chargers spread across 41 cm compartments, each behind its own key.
What does not change with the number of doors
Every door has its own lock and key. The 2-, 4- and 6-door lockers also come with one removable shelf per door. All of them assemble with screws in under 15 minutes per locker and carry a 3-year guarantee. If you would rather not assemble them, we also sell them ready-assembled, on a pallet left at the kerbside, but only within Spain (not the Canary Islands, Ceuta or Melilla); elsewhere, the UK included, they come flat-packed.
How do you combine them in one changing room?
Take a factory with 40 operatives. Half change their clothes completely and the other half only drop off a rucksack. The first group needs 10 two-door lockers: 20 compartments over 6.5 m of wall. For the second there are two options. Five 4-door lockers give exactly 20 compartments in 3.25 m; four 6-door lockers give 24 in 3.88 m, leaving four free for new starters. In total, between 9.75 and 10.38 m of wall.
Because the 2-, 4- and 6-door lockers share the same height and depth, the row stays level even when you mix models. People also need somewhere to sit while they change, and TwinThink benches come in 90 cm and 150 cm lengths. If you are fitting out a whole changing room, ask for a quote for several lockers with the headcount and wall length you have worked out. We usually reply the same working day.
