Nursery space requirements in England: how much space per child, and how to work out what a building will take

The short answer: EYFS space per child

The rule is in paragraph 3.83 of the EYFS statutory framework for group and school-based providers. It is dated 13 July 2026 and effective from 1 September 2026:

"The premises and equipment must be organised in a way that meets the needs of children. Providers must meet the following indoor space requirements where indoor activity in a building(s) forms the main part of (or is integral) to the provision: - Children under two years: 3.5m2 per child. - Two-year-olds: 2.5m2 per child. - Children aged three to five years: 2.3m2 per child."

Where the rule comes from

The framework is statutory and published by the Department for Education on gov.uk. Childminders have a separate framework. Paragraph numbers changed in the 2026 edition, so older guides may cite a different number.

Who checks it

Ofsted checks it, at the registration visit, before you can open. Its guidance on the registration visit says that for nurseries the inspector will check "how much space you have for each child", that you understand "the number and age of children you can care for", and "how you will organise your space to meet the children's learning, development and welfare needs".

What counts as usable space (and what doesn't)

Footnote 67 to paragraph 3.83 defines the area that counts:

"These judgements should be based on useable areas of the rooms used by the children, not including storage areas, thoroughfares, dedicated staff areas, cloakrooms, utility rooms, kitchens and toilets."

So the starting point is the clear floor of the rooms children actually play, learn and rest in. Toilets, nappy-changing areas, kitchens, laundries, stores, staff rooms, offices, cloakrooms and corridors don't count, however much the children use some of them.

Why gross floor area is not capacity

Agents' particulars usually give a whole-unit figure that includes walls, stairs, corridors, toilets and everything else the footnote excludes. Dividing it by 2.3 overstates capacity. Measure the usable rooms on a plan, room by room.

On a plan, we measure each room the children will use and then take out the parts that can't be used for play: the swing of doors and the route between them, fixed joinery and built-in cupboards, radiators and columns. Alcoves and bay windows count only where children can actually use the space. The figure we end up with is usually lower than the one in the particulars, which is why we work room by room.

Thoroughfares: when a room you walk through loses area

The footnote excludes "thoroughfares". If children, staff or parents have to cross one playroom to reach another, or to reach the toilets or the garden, part of that playroom is a route, not play space. Layout matters as much as size: two rooms of the same area can give different numbers depending on where the doors are.

Working it out: from square metres to places

Once you know the usable area of each room and which age group will use it, the arithmetic is simple. Divide the area by the figure for that age band and round down, because you can't register part of a child.

The DfE's guidance on establishing school-based nursery provision gives two worked examples:

"26 pre-school children (3 to 4 years) would need a minimum usable area of 60m²" "26 toddlers (2 to 3 years) would need a minimum usable area of 65m²"

Age mix changes everything

The same room takes different numbers depending on who uses it. As an illustration of the arithmetic only: a playroom with 35 m² of usable floor would meet the minimum for 10 under-twos (35 ÷ 3.5), 14 two-year-olds (35 ÷ 2.5) or 15 three-to-fives (35 ÷ 2.3 = 15.2, rounded down). Room allocation is a business decision as well as a design one.

When we test a building, we usually show two or three ways of allocating rooms to age groups rather than a single answer. Each gives a different number of places and a different staffing pattern, and the right choice depends on local demand and your business plan as well as the floor area.

Space is one limit; staff ratios are the other

Floor area sets one ceiling and staffing sets another. The ratios are in paragraphs 3.47 to 3.51 of the same framework. For example, for under-twos "There must be at least one member of staff for every three children", and for two-year-olds "There must be at least one member of staff for every five children". Paragraph 3.47 says the ratios "apply to the total number of staff available to work directly with children, across the whole provision, not just each room". Read the framework for the full rules, including qualification requirements and the different ratios for three-and-overs.

Outdoor space doesn't add places

Paragraph 3.84 is explicit:

"Where the space standards are applied, providers cannot increase the number of children on roll because they additionally use an outside area."

The DfE consulted in May 2025 on counting free-flow outdoor space. The framework in force from September 2026 still contains paragraph 3.84 as quoted above.

Our free EYFS capacity calculator is a spreadsheet: you enter each room's usable floor area and age band, and it shows the maximum places per room and per age band, rounded down room by room. It also gives the minimum staff in ratio as a reference. Get it from the free checklist page. It comes alongside the free "Will this building work?" checklist for nursery founders.

The rooms that take space before the playrooms

Several rooms don't count towards capacity but still have to fit in the building.

Baby room

Paragraph 3.87:

"There should be a separate baby room for children under the age of two. However, providers must ensure that children in a baby room have contact with older children and are moved into the older age group when appropriate."

DfE school-based nursery guidance adds a benchmark (not a legal requirement for private nurseries): "Where possible, it is recommended that the number of children in the baby room (children under 2 years old) does not exceed 12 children."

Sleep

Paragraph 3.86 sets safer-sleep requirements for children under two, including: "Babies aged 12 months and under must only be placed to sleep in a cot." and "The recommended room temperature for babies is 16 – 20˚C." The DfE's non-statutory Early Years Design Guidance (July 2026, written for school-based nurseries) gives a sleep room of 13 m² as an example, noting: "Example sleep room size is based on 6 sleeping in cots."

In converted buildings, sleep areas tend to work best in a quiet room next to the baby room, where staff can see and hear the children easily and the temperature can be kept steady. They work less well on a busy route, next to the kitchen or plant, or in a room that overheats in summer.

Toilets and nappy changing

The EYFS doesn't give a number. Paragraph 3.88 requires that "There is an adequate number of toilets and hand basins available - there should usually be separate toilet facilities for adults" and that "There are suitable hygienic changing facilities for changing any children who are in nappies."

For a benchmark, the DfE school-based nursery guidance recommends "age-appropriate low-level toilet seats and wash hand basins with a ratio of 1 per 10 pupils or part thereof". For staff toilets it says: "For minimum ratios, refer to Workplace (Health, Safety, and Welfare Regulations) 1992" (legislation.gov.uk), and adds: "Access to an accessible toilet is also required."

At the registration visit, Ofsted checks "that there are enough suitable kitchen, toilet and nappy-changing facilities".

Red flag: in an existing building, the drainage often decides where new toilets and changing areas can go. If the drains are far from the rooms you want to use, the layout or the cost of the works can change, so check this early.

Kitchen, staff room, parent room and storage

Paragraph 3.89 requires, among other things, that "There is an area where staff may talk to parents and/or carers confidentially" and "There is an area for staff to take breaks away from areas being used by children." Add a kitchen or milk kitchen, laundry, office, cloakroom and storage. The DfE design guidance gives example sizes for school-based settings, such as a 13 m² parent/meeting room and a 4 m² store; these are not requirements.

Outdoor space

Paragraph 3.85:

"Providers must provide all children with daily access to an outdoor play area. If that is not possible, they must ensure that outdoor activities are planned and taken for all children on a daily basis (unless circumstances make this inappropriate, for example unsafe weather conditions)."

Ofsted's registration guidance says it checks "that the children have access to outdoor play (this does not necessarily have to be on the premises), and any necessary arrangements for this".

For school-based nurseries, DfE guidance gives a non-statutory outdoor benchmark for nursery children aged 3 or 4 in mainstream schools: a "Combined minimum net area" of "5m² per child".

An on-site garden is usually simpler day to day: staff can take children out in small groups without leaving the building. Using a nearby park can work, but it needs a safe route, enough staff for every trip and a plan for each day, and Ofsted checks those arrangements. We treat it as a question of safety and routine as well as space.

Space is necessary, not sufficient

A building can meet the m² figures and still fail as a nursery. The framework itself requires, at paragraph 3.80, that premises "including overall floor space and outdoor spaces, are fit for purpose and suitable for the age of children cared for". Paragraph 3.81 requires "An emergency evacuation procedure", fire detection, and that "Fire exits must be clearly identifiable, and fire doors free of obstruction and easily opened from the inside."

Then there is planning: whether the building can lawfully be used as a nursery at all. That is the subject of our guide to nursery use class and planning permission.

That is why we look at the whole building, not only the room areas. A building can have enough usable floor and still be hard to make work: babies may have to go on an upper floor, there may be only one way out, the toilets may be far from the playrooms, or there may be no practical outdoor arrangement. Any one of these can change the number of places, the cost of the works or whether the building works at all.

Check a building before you commit

Measure usable area, test age mixes, check the rooms that don't count, then check planning, fire and outdoor play, all before you sign. The free "Will this building work?" checklist turns those steps into questions for nursery founders.

If you have a specific building in mind, our Nursery & School Premises Sprint is an architect-led check of that building before you sign: room-by-room capacity and a test-fit. We are architects, not contractors.
