UK Cake Tin Sizes Reference
Choosing the right tin size matters — too small and your cake overflows, too large and it bakes flat. This guide covers the most popular round and square UK cake tin sizes with volumes, portion counts, and how much batter you'll need for each.
Round Cake Tin Sizes
| Size (inches) | Size (cm) | Volume (litres) | Batter Weight (g) | Portions |
|---|---|---|---|---|
| 6″ | 15 cm | 1.2 | 500–600 | 8–10 |
| 7″ | 18 cm | 1.7 | 700–850 | 12–14 |
| 8″ | 20 cm | 2.2 | 900–1,100 | 14–18 |
| 9″ | 23 cm | 2.8 | 1,100–1,350 | 18–24 |
| 10″ | 25 cm | 3.5 | 1,400–1,700 | 24–30 |
| 11″ | 28 cm | 4.2 | 1,700–2,000 | 30–36 |
| 12″ | 30 cm | 5.0 | 2,000–2,400 | 36–44 |
| 13″ | 33 cm | 5.9 | 2,400–2,800 | 44–52 |
| 14″ | 35 cm | 6.8 | 2,800–3,200 | 52–62 |
Volumes assume a standard depth of approximately 7.5 cm (3″). Batter weight is for a Victoria sponge-type recipe.
Square Cake Tin Sizes
A square tin holds roughly 25% more batter than a round tin of the same nominal size. As a rule of thumb, a square tin is equivalent to a round tin two inches larger — for example, an 8″ square holds about the same as a 10″ round.
| Size (inches) | Size (cm) | Volume (litres) | Batter Weight (g) | Portions |
|---|---|---|---|---|
| 6″ | 15 cm | 1.7 | 700–850 | 12–16 |
| 7″ | 18 cm | 2.3 | 950–1,100 | 16–20 |
| 8″ | 20 cm | 3.0 | 1,200–1,450 | 20–25 |
| 9″ | 23 cm | 3.8 | 1,500–1,800 | 25–32 |
| 10″ | 25 cm | 4.7 | 1,900–2,250 | 32–40 |
| 12″ | 30 cm | 6.8 | 2,700–3,200 | 48–60 |
