Here Is How To Know How Many Flowers To Get For A Wedding


Wedding bouquets

  1. Determine the type and size of bouquet you’ll make for the wedding
  2. Some common flower arrangements for wedding bouquets include rose, hydrangea, baby’s breath, or mixed flowers
  3. For a bouquet of mixed flowers, you’ll need 10 flowers for a small arrangement, then increase it by another 10 flower stems as the size of the bouquet also gets larger; for example, prepare 20 flowers for a medium-sized bouquet and 30 flowers for a large wedding bouquet of mixed flowers
  4. For wedding bouquets made of roses, you’ll need about 12, 20, or 25 flowers to make a small, medium, or large rose wedding bouquet respectively
  5. For wedding bouquets made of hydrangeas, allocate 3, 5, or 8 flowers to make a small, medium, or large hydrangea wedding bouquet respectively
  6. For wedding bouquets made of baby’s breath, you’ll need a bunch for a large bouquet, half for a medium-sized baby’s breath wedding bouquet, and ¼ of a bunch for a small bouquet
  7. The bride may need more flowers as she’ll carry the biggest bouquet with focal flowers, secondary flowers, some greens, and fillers
  8. Bridesmaids may carry small bouquets that will complement the bridal bouquet, so count the number of bridesmaids and multiply it to the bouquets you’ll need to make
  9. The mothers of the bride and groom may each carry a bouquet, but it’s more customary for them to wear a corsage


Wedding corsages and boutonnieres

Please read how to make wedding corsages to know how many flowers you’ll order for each arrangement. Typically, one flower is enough as the primary flower, but some arrangements have as many as six flowers per corsage. 

  1. Determine how many corsages and boutonnieres are needed in the wedding; the boutonnieres usually depend on the number of groomsmen and one unique boutonniere for the groom 
  2. A typical corsage can use two focal flowers, two secondary flowers, two fillers, and one greenery stem
  3. A typical arrangement for a boutonniere can use one focal flower, two secondary flowers or fillers, and one greenery


Wedding floral decors

Besides bouquets, you’ll need to know how many decors you’ll have at the wedding to calculate the flowers you’ll need for the event effectively. 

  1. Flower arrangements are often found on centerpieces, so you can consider multiplying the floral centerpieces by the number of tables you’ll have at the reception
  2. If you’re planning on using floral arrangements on the aisle, pews, chairs, columns, stairs, arch, or fabric draping, then you must also count for them to know how to calculate the number of flowers you’ll need for the decors alone
  3. One small vase for the table will need 10 stems; then you can increase the number by 10 as the size of the flower centerpiece gets bigger; 20 stems for medium or 30 stems for a large-sized flower centerpiece
  4. Smaller flower arrangements for decors will need 8 to 16 flowers, spending on the size of the arrangement and where you’ll put them 


What Is The Average Size Of A Bridal Bouquet?

A bridal bouquet range from 6 to 12 inches wide and 18 to 20 inches long. It is expected to be bigger than the bouquets for the bridesmaids, but in some weddings, only the bride has a bouquet, and the bridal party will wear corsages instead.

What Size Should A Wedding Centerpiece Be?

The size of your floral wedding centerpiece depends on the vase size. You can expect that it will range from 4 by 4 inches to 5 by 5 inches, depending on what is suitable for the tables at the reception. 

Mason jars with flowers are also becoming popular as wedding centerpieces because of the small size that won’t take space on the table or obstruct the view of the guests. Some weddings even have the floral centerpieces hanging instead of arranging them in a vase.


What Is A Reasonable Amount To Spend On Wedding Flowers?

You can allocate up to 10% of your total wedding budget to spend on wedding flowers. Of course, it can be smaller or higher, depending on how many flowers you’ll need and where you’ll be using them.

A tip to save money is to mix in some fake flowers, especially on the decors. You can also use other materials such as ribbons, fabrics, garlands, or lights instead of depending on floral arrangements alone. 



And that’s it! We’ve just learned how to calculate how many flowers for a wedding by knowing how many and what size bouquets, arrangements, and decors you’ll need. 

Each bouquet can start with ten flowers, as many as six flowers per corsage, and at least ten flowers per floral centerpiece. We hope this gave you a quick estimate; leave us a question if you have any.
