How to Determine the Size of Flower Arrangements for a Table

Measure the table and note its shape. Mimic the shape of the table when designing the arrangement. A round table, 54 inches in diameter, is well suited to a round arrangement that starts in a 12-inch vessel with the arrangement extending 2 to 4 inches past the vessel.

Determine the purpose of the arrangement. For example, a purely decorative vignette of table and flowers, such as a table in an entry, requires that the size of the arrangement is large enough to present as a substantial room element. Dave Barritt, master designer/owner of Salmon Arm Florists, suggests, "If it’s decorative only, the sky is the limit. Make it any size."

Clarify the type of food service to determine the space available for the arrangement on dining tables. Family service will necessitate room for serving bowls, so familiarizing yourself with the menu is helpful.

Choose the style of table setting before finalizing the arrangement size. Formal style requires several glasses and side plates per person and may leave little room for a flower arrangement.

Select the height of the arrangement as below the sight line of guests on opposite sides of the table if the table is narrow enough for them to talk to each other, or above the sight line if the table is too wide for conversation.

Set the table with all the required plates, bowls, glasses and stem-ware and test the size of various vessels in the available space. Stand back and look at the table and possible arrangment size and if it is pleasing to your eye, it is probably the right size.
