Every way to seat 10

The chart below shows the smallest cake that covers 10 guests for each shape and slice size — all from the same Wilton figures the calculator uses. "Party" slices are 1½ × 2 in slice; "wedding" slices are the slimmer 1 × 2 in slice, which is why the wedding options run smaller.

Option Smallest fit Seats about
Round, party slices 6" round 12
Square, party slices 6" square 12
Round, wedding slices 6" round 12
Sheet, party slices 7×11" sheet 24

A single cake covers this comfortably. If you'd rather make a moment of it, any two-tier combination whose counts add past 10 works — the calculator below totals tiers live as you pick them. Treat 10 as a minimum: end pieces and uneven cuts always cost a few servings, and leftover cake has never been a problem.

Frequently Asked Questions

What size cake do I need for 10 guests?

Cutting party slices (1½ × 2 in slice), a single 6" round seats about 12 — enough for 10. A single 7×11" sheet sheet (24 party servings) also covers it and is the easiest to cut and transport.

What size cake for 10 wedding guests?

Wedding slices are slimmer (1 × 2 in slice), so cakes stretch further: a single 6" round seats about 12. Wedding planners usually add a few servings of margin on top for cutting loss.

Should I round up for 10 guests?

Yes — treat 10 as the minimum. End pieces, uneven cutting and second helpings all reduce the real yield, so a size (or tier) above the exact fit is the safe choice. Leftover cake keeps; running short doesn't fix itself.
