CAKE SIZE GUIDE

What Size Cake Box Do I Need? A Complete Guide

Choosing the right cake box size is one of the most important parts of protecting your cake and presenting it professionally. Whether you’re packaging a simple 6-inch cake or a tall tiered design, the right box ensures your cake arrives safely and looks exactly how you created it.

How to Choose the Right Cake Box Size

When selecting a cake box, you need to consider two things:

1. Cake diameter (width)
2. Cake height (including decorations)

👉 Always choose a box 1–2 inches bigger than your cake to prevent smudging and damage.

What size box do I need?

✦
Sizing rule of thumb: choose a box at least 1–2" wider than your cake (or cake board) and at least 1" taller than your finished cake including toppers, so the lid closes without touching your decorations.

Find your cake size, then pick the box that matches your cake’s total height, including toppers. Tap any box to shop it.

✦
Round cakes also fit square boxes. For 12" round cakes, our 13" and 14" square boxes give you the room you need.

✦
Measuring square cakes: measure side to side, including your cake board. A square box only needs to be 1–2" wider than that. Avoid putting square cakes in round boxes, since the corners need the full diagonal width.

Common Cake Box Sizing Mistakes

  • Choosing a box that is too short (damages toppers and decorations)
  • Choosing a box that is too tight (smudges frosting)
  • Not accounting for cake boards or bases
  • Using weak boxes that collapse during transport

What Size Box for Tall or Tiered Cakes?

Tall cakes require extra height that standard bakery boxes do not provide.
For cakes with multiple tiers, florals, or toppers, you should use a box that is significantly taller than the cake itself to avoid damaging the design.
