What does AHDB Dairy 2024 say about cubicle sizing?
AHDB Dairy's 2024 housing guidance ties cubicle dimensions to cow size — specifically wither height and diagonal body length — rather than treating "Holstein" or "Jersey" as a single number. For a 650kg (1,433lb) Holstein the recommendation is 2.4m (7'10") total length, 1.2m (3'11") centre-to-centre width, neck rail at 1.15m (3'9") and brisket board 1.7m (5'7") from the kerb.
The numbers come from welfare research showing cows lunge forward 0.6–0.9m (2ft-2'11") when rising and need a clear bed length of around 1.8m (5'11") to lie comfortably with their legs tucked. Cubicles sized for an "average" 1990s Holstein (typically 2.2m × 1.1m / 7'3" x 3'7") are now too small for modern Holsteins which routinely weigh 700kg+ (1,543lb+) and stand 1.45m (4'9") at the wither.
The guidance is welfare-led but ties directly to commercial outcomes: cows in undersized cubicles spend less time lying, drop yield (around 1.5 litres / 0.33 UK gal per hour of lying-time lost), and develop more hock and knee lesions. Sizing is one of the cheapest yield levers a dairy unit has. WCCP precast cubicle beds, cubicle end walls, heelstone coping and water troughs are cast to AHDB 2024 dimensions across the agricultural sector.
What are the cubicle dimensions for each breed?
Holstein-Friesian: 2.4m × 1.2m (7'10" x 3'11"). Jersey: 2.2m × 1.1m (7'3" x 3'7"). Beef suckler (medium): 2.4m × 1.2m (7'10" x 3'11"). Continental beef: 2.5m × 1.25m (8'2" x 4'1"). Heifers: scale 90% of mature herd dimensions. The width given is centre-to-centre between divisions; the bed itself is 50–80mm (2in-3in) narrower once division thickness is accounted for.
| Breed / type | Length | Width (c/c) | Neck rail height | Brisket board |
|---|---|---|---|---|
| Holstein-Friesian (650kg / 1,433lb) | 2.40m (7'10") | 1.20m (3'11") | 1.15m (3'9") | 1.70m (5'7") from kerb |
| Holstein (large, 750kg+ / 1,653lb+) | 2.50m (8'2") | 1.25m (4'1") | 1.20m (3'11") | 1.75m (5'9") from kerb |
| Jersey (450kg / 992lb) | 2.20m (7'3") | 1.10m (3'7") | 1.05m (3'5") | 1.55m (5'1") from kerb |
| Crossbreed (Holstein × Jersey) | 2.30m (7'7") | 1.15m (3'9") | 1.10m (3'7") | 1.60m (5'3") from kerb |
| Beef suckler (medium frame) | 2.40m (7'10") | 1.20m (3'11") | 1.20m (3'11") | 1.70m (5'7") from kerb |
| Continental beef (Limousin, Charolais) | 2.50m (8'2") | 1.25m (4'1") | 1.25m (4'1") | 1.80m (5'11") from kerb |
| Dairy heifers (in calf) | 2.20m (7'3") | 1.10m (3'7") | 1.05m (3'5") | 1.55m (5'1") from kerb |

How does body weight change cubicle dimensions?
As a rule of thumb, cubicle length should equal 1.83 × hook bone height, and cubicle width should be 0.83 × hook bone height. For a 650kg (1,433lb) Holstein with a 1.30m (4'3") hook bone height, that gives 2.38m × 1.08m (7'10" x 3'7") — close to the 2.4m × 1.2m (7'10" x 3'11") standard once a small margin is added for movement.
Modern dairy genetics have added 50–80kg (110-176lb) of mature weight per decade since the 1980s. A 1990s Holstein at 600kg (1,323lb) fitted comfortably in a 2.3m × 1.15m (7'7" x 3'9") cubicle. Today's 720kg (1,587lb) cow doesn't, and you'll see her lying diagonally, dunging on the rear of the bed, or refusing to enter at all.
We recommend measuring 10 representative cows in your herd — wither height, hook bone height and diagonal body length — before specifying a new cubicle row. The five-minute measurement saves a costly mistake.
How high should the neck rail be?
Set the neck rail at 0.83 × wither height — 1.15m (3'9") for a typical Holstein, 1.05m (3'5") for a Jersey, 1.20m–1.25m (3'11"-4'1") for Continental beef. Position it 1.7m (5'7") forward of the rear kerb (or matched to the brisket board distance for the breed). The rail's job is to position the cow when she enters so she dungs in the passage, not on the bed.
Too low and the cow refuses to enter — you'll see chains of cows queuing in the passage with the cubicles empty. Too high and she stands half-in, dunging on the front of the bed. The "knee test" works: a cow should be able to stand square in the cubicle with her front knees on the bed and her hocks just inside the rear kerb.
All WCCP cubicle divisions ship with adjustable neck rails on a swedge tube fixing. Typical adjustment range is ±100mm (4in) in 25mm (1in) increments, which covers most herd shifts.
Where does the brisket board go?
The brisket board sits 1.7m (5'7") from the rear kerb for a Holstein, 1.55m (5'1") for a Jersey, 1.75–1.8m (5'9"-5'11") for Continental beef. Maximum height 100mm (4in) above the bed, with a radiused or chamfered top edge. Its purpose is to control where the cow's chest rests — pushing her hindquarters back so she dungs in the passage.
Common mistakes: too high (causes hock lesions on rising), too sharp (knee abrasions), too far back (cow over-shoots and lies with chest in the lunge space), or no board at all (cow drifts forward and dungs on the bed). A 100mm (4in) precast board with a 25mm (1in) radius edge is the AHDB-aligned standard.
We supply brisket boards either cast integrally with the bed (deep-bed sand systems) or as bolt-down precast strips (mattress and rubber-mat systems). The bolt-down version allows seasonal adjustment for in-calf heifers joining the milking herd.
How much lunge space does a cow need?
A cow needs 0.6m–0.9m (2ft-2'11") of unobstructed lunge space forward of the brisket board. For an open-fronted cubicle that means 0.6m (2ft) clear to a wall; for head-to-head pairs the total cubicle-to-cubicle length should be 4.8m (15'9", for Holsteins) so each cow has unobstructed lunge into the opposing cubicle.
Cattle don't rise like horses. They throw their heads forward and downward to shift their centre of gravity, then heave the hindquarters up, then the front. Block that head movement with a wall, gate or solid head rail and the cow can't rise — she'll either refuse to lie or struggle when she does, increasing injury risk.
Open-fronted (against an outside wall) and head-to-head (paired) layouts both work. Avoid forward-blocked layouts — sometimes seen in retrofitted older buildings — unless you can guarantee 1.0m+ (3'3"+) of clear lunge space in front.
What are the 5 most common cubicle sizing mistakes?
In order of frequency: cubicles too short for modern Holsteins, neck rail too low or too far back, brisket board too high, head-to-head pairs only 4.5m (14'9") total, and mixing dairy and dry cow groups in the same cubicle size. Each one shaves litres off yield or adds vet bills.
- Old beds, new cows. A 2.2m (7'3") bed designed for 1995 Holsteins is too short for 2026 Holsteins. Measure your cows.
- Neck rail set for an empty bed. Add bedding depth to the height. A 50mm (2in) sand or mattress depth means the rail is effectively 50mm (2in) lower than spec.
- Brisket board too tall. Above 100mm (4in) the board catches the cow's foreleg as she rises. We see hock lesions in herds with 150mm (6in) timber boards.
- Head-to-head too short. 4.5m (14'9") total isn't enough for two Holsteins to lunge. Specify 4.8m (15'9"), or 5.0m (16'5") for large-frame herds.
- One size for all groups. Heifers, dry cows and milkers don't fit one size. Group sizing increases lying time and yield in every benchmarked study.
Cubicle sizing checklist (10 points)
Tick all ten and your cubicles will pass the AHDB welfare audit and maximise lying time. Most issues we see on farm visits are one of these ten items.
- Measured 10 representative cows for wither height and diagonal body length
- Cubicle length matched to breed (2.4m / 7'10" Holstein, 2.2m / 7'3" Jersey, 2.5m / 8'2" Continental beef)
- Cubicle width centre-to-centre matched to breed (1.10m–1.25m / 3'7"-4'1")
- Neck rail at 0.83 × wither height (1.05m–1.25m / 3'5"-4'1" typical)
- Brisket board 1.55m–1.80m (5'1"-5'11") from rear kerb, max 100mm (4in) tall, radiused edge
- 0.6m+ (2ft+) clear lunge space forward, or 4.8m (15'9") head-to-head total
- Bedding depth allowance added to neck rail and brisket board calculation
- Heifer / dry cow / milker groups sized separately where housed in different rows
- Adjustable neck rail fixings for seasonal or breed shifts
- Passage width minimum 3.0m (9'10") behind cubicles for cow flow and scraper clearance
Frequently asked questions
What is the standard UK cattle cubicle size for Holsteins?
A standard UK Holstein-Friesian cubicle is 2.4m long by 1.2m wide (7'10" x 3'11"), with the neck rail 1.15m (3'9") above the bed and the brisket board 1.7m (5'7") forward of the rear kerb. AHDB Dairy 2024 guidance treats this as the baseline for cows of 600–700kg liveweight (1,323-1,543lb).
How do I size a cubicle for Jersey cows?
Jerseys are smaller — typically 380–500kg (838-1,102lb) — so cubicles are reduced to 2.2m long by 1.1m wide (7'3" x 3'7"), with neck rail at 1.05m (3'5") and brisket board 1.55m (5'1") from the kerb. Oversizing a Jersey cubicle leads to soiled beds and elevated cell counts.
What size cubicle does a beef suckler cow need?
Suckler beef cubicles run 2.4m × 1.2m (7'10" x 3'11") for medium frames and 2.5m × 1.25m (8'2" x 4'1") for Continental breeds (Limousin, Charolais, Simmental). Neck rail sits at 1.20m–1.25m (3'11"-4'1") to accommodate the deeper chest and longer rising arc compared with a dairy cow.
How high should the neck rail be?
For a 650kg (1,433lb) Holstein, set the neck rail at 1.15m (3'9") above the bed surface. The rule of thumb is 0.83 × wither height. Too low and cows refuse to enter; too high and they stand half-in, dunging on the bed. Adjust seasonally if bedding depth changes.
Where should the brisket board sit?
The brisket board should be 1.7m (5'7") from the rear kerb for a Holstein, 1.55m (5'1") for a Jersey, and 1.75m–1.8m (5'9"-5'11") for a large Continental. Maximum height 100mm (4in) and rounded — a sharp or tall brisket board causes hock and knee lesions when the cow rises.
Can I retrofit cubicles to a different breed?
Yes. Most WCCP cubicle divisions are bolt-down or socketed, so length, width and neck rail can be repositioned. Brisket boards and head rails are typically replaced rather than moved. Allow half a day per row of 20 cubicles for a full reconfiguration.
What does AHDB say about lunge space?
AHDB Dairy 2024 specifies 0.6m (2ft) of clear lunge space forward of the brisket board for an open-fronted cubicle, or a head-to-head pair of 4.8m (15'9") total length. Cows lunge forward 0.6–0.9m (2ft-2'11") when rising, and obstructing that motion causes refusals and injuries.
