You’ll stand there with the menu open, thinking — is 1 kg enough for everyone, or should I take the bigger one? I know that feeling. Nobody wants to cut a cake into paper-thin slices in front of guests, and nobody wants half of it sitting in the fridge for four days either.
So let me tell you plainly what size to order. A 1 kg cake serves 8 to 10 people. Everything below that, above that, I’ll go through one by one. All our cakes at Cakery Crush are eggless, and everything here applies the same way — eggless sponge cuts and serves exactly like any other.
Why does cake size matter?
The cake is the last thing people eat and the thing they remember. If it runs short, that’s what gets talked about afterwards. If it’s too big, you’re carrying it home, finding fridge space, eating it for breakfast three days running. Get the weight right and the whole evening feels planned.
My mother used to say, বেশি হলে ক্ষতি নেই, কম হলে লজ্জা — beshi hole khoti nei, kom hole lojja — too much does no harm, too little brings shame. She was talking about rice on a plate, but it works for cake.
How many people does a 1 kg cake serve?
A 1 kg cake serves 8 to 10 people. This is the size most people order, and for good reason. A birthday at home, a small team in the office, a few neighbours in the evening. Enough that the children can come back for a second piece without you counting.
A 0.5 kg cake serves 4 to 6 people. Two of you, or a small family dinner, or tea in the evening. It finishes the same day and nothing goes to waste. This is the size most bento cakes come in — one message, one small cake, no leftovers.
What size cake for 20 people?
Take 2 kg. A 2 kg cake serves 20 to 24 people — office celebrations, milestone birthdays, a proper house party. It’s big enough on top to carry a real design, so this is where custom work starts to look worth it.
For 12 to 16 people, 1.5 kg is the one. House party, extended family, everyone’s cousins turning up. Good size, sensible price, and you can cut proper slices instead of slivers. This is the usual size for anniversary cakes — enough for both families to sit and eat.
What size cake for 30 to 50 people?
A 3 kg cake serves 30 to 35 people. Large birthdays, family functions, big office events. This one looks like something when it comes to the table, and there’s room on it for detailed work.
A 4 to 5 kg cake serves 40 to 60 people. Weddings, corporate events, long guest lists. At this size you can go multi-tier, and fondant cakes hold their shape best for tall work like that.
Do I need a multi-tier cake for 50+ guests?
For a really big crowd, don’t order one giant cake. Take a 2-tier or 3-tier, or a real tier with dummy tiers underneath, or two cakes in the same design cut from opposite ends. Serving goes twice as fast and the table looks better. One enormous single cake is heavy to move, hard to cut evenly, and somebody always ends up with the middle bit.

How to choose the right cake size
Add two or three extra slices. Somebody’s slice will break while you’re cutting, or one more guest will walk in at the door. Always keep the buffer.
Think about the rest of the food. Heavy dinner with sweets already on the table? Go one size down. Cake is the only dessert? Go up — people will want a proper piece.
Chocolate truffle fills you faster than vanilla. Rich, dense chocolate cakes get eaten in smaller slices. Light sponge and fresh fruit cakes go quicker, so take a little more.
For a big crowd, cream cuts cleaner than fondant. Fondant is for looks and for tall tiers. If fifty people are queueing with plates, a cream cake serves faster.
Children’s parties, take one size up from what you calculated. They’ll ask again. They always ask again.
Frequently asked questions
How many people does a 1 kg cake serve? A 1 kg cake serves 8 to 10 people, cut into standard slices. If it’s the only dessert after a light meal, count on 8.
What size cake do I need for 20 people? Order 2 kg. That gives 20 to 24 servings, which leaves you a small buffer for extra guests or a broken slice.
Is a 1 kg cake enough for 15 people? No. For 15 people take 1.5 kg. A 1 kg cake stretched over 15 guests means very thin slices, and it will be noticed.
Does an eggless cake serve fewer people than a regular one? No. Eggless sponge is the same density and cuts the same way. A 1 kg eggless cake gives you the same 8 to 10 servings.
Should I order round or square? Square cakes give slightly more neat portions because they cut in a grid. For large guest counts a square or rectangular cake is easier to serve evenly.
How far in advance should I order? For 1 to 2 kg, two or three days is comfortable. For anything above 3 kg, multi-tier, or heavy custom work, give us a week.
