CLASSROOM LAYOUT PLANNER
Classroom layout planner, desk by desk.
Arrange desks, boards and storage in 2D, check the room's size per pupil and its walkways against published figures, then look at the board from a pupil's seat in 3D.

CLASSROOM SIZE
Is your classroom big enough for the class?
Published figures for classroom size differ by country and state. England's area guidelines give sizes for a class of 30 [1]; Arizona sets a floor area per student [2] and California a room size [3]. Compare your room with all three.

BB103 sizes a space as a base area plus an area per pupil, so per-pupil figures scaled from its 30-pupil sizes are approximate for much smaller or larger groups. Arizona's figure is a minimum for a district's classrooms taken together, not for each room.

SEATING ARRANGEMENTS
Which seating arrangement fits your room?
Desks take less room than the walkways around them. Where a pupil sits, the walkway is measured from a line 483 mm (19 in) out from the desk edge [5], and an accessible route is 915 mm (36 in) wide [4]. Try rows, pairs, groups and a horseshoe.
Seating arrangement explorer
A rectangular room with the board on one wall. Pick an arrangement and a desk size; the template's desk is 610 × 457 mm.
Desks that fit · pairs
48 desks fitAt least 3 of them accessible (5%), 2.08 m² of floor a desk
- Across the room
- 4 × 1,220 mm pairs + 3 aisles × 914 mm + 1 route × 915 mm = 8.54 m of 10.50 m
- Each row, front to back
- 457 mm desk + 1 × 483 mm chair line + 305 mm (under 12 ft long) walkway = 1,245 mm
- Board to back

- Accessible desks
- At least 3: 5% of 48, rounded up. Give each a 760 × 1,220 mm (30 × 48 in) clear floor space on the route
Every walkway in the drawing is at its published minimum; real rooms need space for doors, storage and how you teach. The explorer puts a 914 mm aisle beside every column of desks, a simplification: the code asks only that each seat's walkway reach an aisle within its length limits, so rows of single desks may fit more than shown. The aisle (914 mm, Minnesota) and the route (915 mm, ADA) are both 36 in; the two sources convert it differently.

| Arrangement | Desks | Accessible, at least | m² per desk | How they stand |
|---|---|---|---|---|
| Rows | 36 | 2 | 2.77 | 6 columns of single desks, 6 rows deep, an aisle beside each column |

HOW IT WORKS
From template to a classroom you can walk through
Every picture on this page is the planner itself, on the classroom template.
Open the classroom template
Daylight classroom is a 10.5 × 9.5 m room with three 1,900 mm windows down one side, a 1,400 mm door at the back and three bookshelves.
- 24 pupil desks in pairs
- Two teaching boards and a teacher's desk
- Resize it, or start blank and draw your own in metres or feet
Arrange desks into rows, pairs or groups
Select a desk on the plan; every change has Undo.
- Type its position, or drag it
- Turn it with the rotation dial, to the angles the item allows, so pairs become groups facing each other
Check the gaps
Space around lists the gap on each side of the selected item, and Plan check lists every flag.
- Open Space around on the desk's item card
- Each side's gap, to the nearest desk, chair or wall
- Where an item carries a published clearance figure, a side below it is flagged with the figure and its source, as guidance
Look at the board from a pupil's seat
Walk the classroom at eye height to check sightlines to the board.

QUESTIONS
Classroom layout questions
How much space does a classroom need per pupil?
It depends on where you are. England's Building Bulletin 103 recommends 55 to 62 m² for a standard classroom of 30 pupils, about 1.8 to 2.1 m² a pupil. Arizona sets a minimum of 25 to 32 ft² (2.3 to 3.0 m²) per student by grade, counted across a district's classrooms, of which only 90% of the area counts for grades 7 and 8 and 85% for grades 9 to 12, and California plans general classrooms of at least 960 ft² (89 m²). [1, 2, 3]
How wide should the aisles between desks be?
In Minnesota's building code, where pupils sit at a desk the walkway is measured from a line 19 in (483 mm) out from the desk edge. The walkway behind a row, an aisle accessway, is at least 12 in (305 mm), plus 0.5 in for each foot beyond 12 ft of length; aisles are at least 36 in (914 mm). An accessible route is 36 in (915 mm) wide (both 36 in; the two sources convert it differently), and may narrow to 32 in (815 mm) for up to 24 in of length. [5, 4]
Which seating arrangement fits the most desks?
It depends on an assumption. The explorer on this page puts a 914 mm aisle beside every column of desks; the code asks only that each seat's walkway reach an aisle within its length limits, so single desks in rows can sit closer than the explorer shows. With that assumption, in the template's 10.5 by 9.5 m room, with 610 by 457 mm desks, a 2 m zone kept clear at the front and the walkway widths above, it fits 48 desks as pairs or as groups of four, 36 as single desks in rows and 31 in a horseshoe; a horseshoe gives up desks for an open middle. [5, 4]
How many accessible desks does a classroom need?
Under the 2010 ADA Standards, at least 5 percent of the work surfaces provided for people other than employees, such as pupil desks and study carrels, are accessible and dispersed through the room. Each has a 30 by 48 in (760 by 1220 mm) clear floor space for a forward approach; tops are 28 to 34 in (710 to 865 mm) high, or 26 to 30 in (660 to 760 mm) for children's use. [4]
Can I plan my own classroom's size and shape?
Yes. Start from the classroom template and resize the room, or start blank and draw your own in metres or feet. Every desk, board and shelf can be moved, turned, duplicated or removed.
Will FloorPlanCraft tell me whether my classroom meets code?
No. Its clearance warnings and these tools are planning guidance from the published figures they name. A layout is a concept for discussion: confirm room sizes, exits and accessibility with your school's facilities team, the building authority and a qualified professional.
Do I need an account?
No. You can open the template, edit it and export it without signing up. Sign in when you want to save versions and publish a view-only link.
Can I use it on a phone?
You can read this page, use both tools and open shared plans on a phone. For drawing and arranging the plan, use a desktop or laptop.
