Cake for 100 Guests: How to Choose the Right Size and Budget
Planning a wedding cake for 100 guests can feel like a puzzle, but it doesn't have to be. The key is to know how many slices you need, what style fits your venue, and how much you’re willing to spend. Below we break down the basics so you can order a cake that looks great, feeds everyone, and stays within budget.
How Big Should the Cake Be?
Most bakers use a serving chart that tells you how many people each tier can feed. A common rule of thumb is:
- One‑tier (6‑inch) cake ≈ 20‑30 guests
- Two‑tier (8‑inch + 10‑inch) cake ≈ 50‑70 guests
- Three‑tier (8‑inch + 10‑inch + 12‑inch) cake ≈ 90‑120 guests
For 100 guests, a three‑tier cake is usually the sweet spot. If you want extra layers for decoration, you can ask the baker to make a smaller tier and fill the gap with a sheet cake or cupcakes.
Cost Factors You Can Control
Wedding cake prices depend on a few things: flavors, design complexity, buttercream vs. fondant, and the bakery’s reputation. Here are three ways to keep costs down without sacrificing style:
- Limit the number of flavors. Offering two or three flavors is plenty. More flavors mean more work and higher price.
- Choose simple decorations. Fresh flowers, fruit, or a minimalist buttercream design cost less than intricate sugar work.
- Consider a “cut‑away” tier. Some couples order a smaller tasting tier to display, then serve a plain sheet cake hidden behind it. This looks fancy but saves money.
On average, a three‑tier cake for 100 guests runs between £1,200 and £2,500 in the UK, but you can find good options below £1,500 if you stay smart about flavors and décor.
Don’t forget extra costs: delivery, set‑up, and a stand or cake board. Ask the bakery for a full quote so there are no surprise fees.
When you meet with a baker, bring a list of must‑haves (like a certain frosting or a color scheme) and a clear guest count. Most bakers will give you a serving chart on the spot, so you can see exactly how many people each tier will feed.
Finally, schedule a tasting at least two months before the wedding. This gives you time to tweak flavors and design before the big day.
With the right tier plan, a realistic budget, and clear communication, your cake for 100 guests will be the perfect centerpiece—delicious, beautiful, and stress‑free.
