Bridesmaid Bouquet Calculator — Flowers & Sizes
Plan bouquet sizes and flower quantities for the bridal party.
How We Calculate This
This calculator estimates bridesmaid bouquet requirements and costs using bridesmaid-sized posies (12-20 stems), not full bridal bouquets.
Formula
- Stems per bouquet = small 12, medium 16, large 22 (≈60-75% of a bride's 25-30 stems)
- Total stems = bridesmaids × stems per bouquet
- Greenery stems = total stems × greenery % (default 40%); flower stems = the remainder
- Grand total (£) = bridesmaid bouquets + flower girl posies + ribbon/wrap
Frequently Asked Questions
A bridesmaid bouquet is typically 12-20 stems (around 15 on average) — roughly 60-75% the size of the bride's 25-30 stem bouquet. In this calculator small ≈ 10-12 stems (junior bridesmaids), medium ≈ 15-18 stems (most popular) and large ≈ 20-25 stems for a fuller posy. All bouquets should complement, not compete with, the bride's. Figures follow UK DIY-wedding floristry guides (e.g. Triangle Nursery); exact counts vary with flower size and style.
Bridesmaid posies are usually loaded with foliage to keep them light and affordable — around 40% greenery, compared with roughly 20% in the bride's bouquet. A common starting point is the 3-5-8 rule: about 3 focal flowers, 5 greenery stems and 8 filler stems (16 total). Use the Greenery Percentage option to split your total into greenery versus flower stems.
Matching bouquets create a uniform look in photos. However, many couples now opt for complementary bouquets - same colour palette but slightly different flowers or sizes. This allows each bridesmaid to have something unique while maintaining a cohesive look.
As a rough UK guide: small bouquets £30-£50, medium £50-£80, large £80-£120. Costs depend heavily on flower choice — roses and peonies cost more than gypsophila and greenery — and seasonal flowers are cheaper. Most florists offer a bridal-package discount. Treat these as indicative typical UK florist pricing; always confirm a quote with your florist.
Flower girls carry small posies (8-12 stems), wands, or baskets with petals. As a UK guide, posies cost around £15-£35, flower wands £10-£25 and petal baskets £10-£20. Keep it light and small enough for little hands. Silk flowers are a practical option for very young flower girls. Prices vary by florist and flower choice.
