Planning Your Wedding Catering
UK wedding catering typically moves through three stages: a canapés and drinks reception while photographs are taken, the wedding breakfast (the formal sit-down meal for day guests), and an evening buffet for those arriving later. Each stage has its own portion logic, and getting the quantities right matters — running out of food is memorable for the wrong reasons, but over-ordering adds cost without adding value.
The Wedding Catering Calculator covers all three stages in one place. For canapés, it calculates how many pieces to order based on the length of your reception and whether canapés are a pre-dinner appetiser or the main food. For the wedding breakfast, it works out covers, bread rolls, and estimated dietary requirements. For the evening buffet, it calculates protein, carbs, salad, and bread roll quantities using UK caterer portion standards.
The Wedding Cake Calculator works out how many servings your wedding cake will provide, or recommends a tier configuration for your guest count. It supports round and square cakes, finger and dessert portions, and the UK tradition of saving the top tier for your first anniversary. Serving counts are based on the industry-standard Wilton cutting method.
All portion sizes and default costs in our tools use UK industry standards — UK caterer guidance for buffet weights, UK bakery conventions for cake portions, and UK mid-range pricing. These figures will not match US or European catering guides.
