This is a guide to approximately how many portions you can expect from cakes of different sizes:

Cake size in inches Approx. 2" x 1" party portions Approx. 1" x 1" finger portions
4" round 4 8
5" round / 4" square 7 14
6" round / 5" square 10 20
7" round / 6" square 15 30
8" round / 7" square 20 40
9" round / 8" square 27 54
10" round / 9" square 34 68
11" round / 10" square 45 90
12" round / 11" square 50 100
12" square 67 134

Party portions are perhaps best for family gatherings or where cake is being served as dessert at a wedding reception (in this instance you may wish to cater for even larger 2″ x 2″ portions). Finger portions are perhaps best for large buffets or children’s party bags.

Remember to allow extra for second helpings (especially if you are offering more than one flavour), or if you would like any left over after the event.

Multi-tiered cakes usually have a 2 or 3 inch difference between tiers depending on design and portions required.

Boxes of cupcakes and cupcake towers can also be provided with a minimum order of 12 per flavour. 


Cakery Bay offers a bespoke service with each cake being designed and handmade to order. Cakes are therefore individually priced according to requirements and will depend on size, flavour and complexity of design. As a guide:

A single tier sponge celebration cake to serve 30 finger portions would be from £70. Novelty shaped cakes and some decoration such as handmade sugar flowers and figures would be at additional cost.

A 3-tier wedding cake to serve 65 finger portions would be from around £300 and would include delivery and set-up at your venue.

Box of 12 cupcakes with buttercream swirl from £30.

Iced all-butter shortbread biscuits from £2 each.

Cupcakes and biscuits can also be individually boxed/bagged and tied with ribbon as favours for weddings, parties or corporate events.
