Every way to seat 50

The chart below shows the smallest cake that covers 50 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 14" round 63
Square, party slices 14" square 63
Round, wedding slices 12" round 56
Sheet, party slices 11×15" sheet 54

A single cake covers this comfortably. If you'd rather make a moment of it, any two-tier combination whose counts add past 50 works — the calculator below totals tiers live as you pick them. Treat 50 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 50 guests?

Cutting party slices (1½ × 2 in slice), a single 14" round seats about 63 — enough for 50. A single 11×15" sheet sheet (54 party servings) also covers it and is the easiest to cut and transport.

What size cake for 50 wedding guests?

Wedding slices are slimmer (1 × 2 in slice), so cakes stretch further: a single 12" round seats about 56. Wedding planners usually add a few servings of margin on top for cutting loss.

Should I round up for 50 guests?

Yes — treat 50 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.
