What is a standard tier size progression?

A common approach is to decrease each tier by 5cm in diameter. For example: 30cm, 25cm, 20cm, 15cm. Each tier is typically 7-10cm tall. This gives a visually balanced, structurally sound cake.

How much batter do I need per tier?

Fill each tier tin to about two-thirds full. Cake batter weighs roughly 1g per cm³, so the usable volume in cm³ gives you a reasonable estimate of batter weight in grams.

Do I need to adjust the recipe for each tier?

Each tier is baked separately, so treat each as an individual cake. Calculate the batter needed per tier and scale your base recipe accordingly using the volume ratios.

How do I support a tiered cake structurally?

Each tier needs internal dowel supports (food-safe plastic or wooden dowels) to bear the weight of the tiers above. The bottom tier needs the most support. Use a cake board between each tier and consider using a central rod for very tall cakes.

How much space should I leave between tiers?

Each tier should be at least 5cm (2 inches) smaller in diameter than the one below it for a proportional look. For example, a three-tier cake might use 30cm, 25cm, and 20cm tins. This size difference ensures each tier is visible and the cake looks balanced.

How We Calculate This

Each tier is calculated as a cylinder: Volume = π × (diameter ÷ 2)² × height. The volumes are summed to give the total, and batter weight is estimated based on filling each tier to two-thirds capacity.

Calculation Steps

Calculate each tier volume: π × r² × h
Sum all tier volumes for total tin capacity
Multiply by ⅔ for usable fill volume
Batter weight ≈ usable volume in cm³ (1g per cm³ density)
