Cutting & Serving Pro Tips

Chill Before You Cut — 20 to 30 minutes in the fridge firms the buttercream so every slice comes out clean and square.

Use a Hot, Dry Knife — Dip a long, thin knife in hot water and wipe it dry between every cut.

Cut Tiers Off the Stack — Lift each tier onto its own board before slicing, and pull the dowels as you go.

Quote by the Serving — Price per serving, not per pan. Quotes stay consistent when a client changes the shape or the number of tiers.

Tall Tiers Change the Math — Everything here assumes 4 in tall tiers. A 6 in double-barrel tier serves about 1½ times as many when cut to the same weight.

Questions

Cake questions, answered.

How many servings are in a cake?

It depends on the slice. Party servings are usually about 1.5 × 2 inches and wedding servings 1 × 2 inches, both from a 4-inch-tall tier. Choose your event in the calculator and it uses the right size.

Do you have printable cake cutting guides?

Yes, for rounds from 4 to 16 inches, including the 6", 8", 10", 12", 14" and 16", or every round size in one PDF. The calculator above also prints a cutting map for the exact cake you build.

Can I put my own branding on a cutting guide?

Bloom shops make cutting guides and care cards in their own Brand Generator style. Prefer Canva? Try our cake cutting guide Canva templates.

How big a cake do I really need?

Start from your guest count, add a few servings for second helpings, and let the calculator suggest the tiers. Our guide How big of a cake do I really need? walks through it.

Is the cake calculator free?

Completely. No sign-up, no account, and the printable template is free too.

Your kitchen's ready. Your shop can be too.
