Flower Arrangement Calculator

Plan a full arrangement by width, depth and height, with a stem count for each level and a cost per arrangement.

Width the arrangement must cover cm

The base plus the spread, so a 30 cm centrepiece is planned across 30 to 36 cm.

Depth the arrangement must cover cm

Finished height cm

From the top of the container to the highest flower.

How full you want it times

One is standard, 0.8 for a loose garden style, 1.3 for a dense domed arrangement.

How much of it is seen times

One for a centrepiece seen from all round, 0.6 for a mantelpiece seen from the front only.

Diameter of one flower head cm

Rose 8 to 10 cm, carnation 5 to 6, hydrangea 15 to 20, dahlia 10 to 15.

Focal flowers as a share of the flowers %

The largest and most expensive blooms. Twenty five percent suits a mixed arrangement.

Foliage stems per flower stem stems

Foliage is cheap and fills space. A generous base of greenery can cut the flower count by a fifth.

Price per flower stem

Your own figure.

Price per foliage stem

Usually bought by the bunch. Divide the bunch price by the stems to get this.

Foam, container hire and mechanics

Per arrangement. Foam, a liner, wire, tape and any hire charge.
