From a recipe to whole bunches
ONE FLOWER AT A TIME
Enter the count of this flower in one design, not the total stems of every flower in the arrangement. The starting bunch size of 10 is editable; use your supplier’s actual pack size.
FROM ONE DESIGN TO FIFTEEN
How many flower stems should you order?
Begin with one tested arrangement.
Count the stems of a single flower variety in your sample design. If one centerpiece uses five garden roses, enter five stems per arrangement. Do a separate calculation for ranunculus, carnations, foliage, and any other ingredients with different pack sizes.
Multiply that recipe by the number of arrangements you will make. Then apply your chosen extra-stem percentage to the combined count. The calculator rounds that requirement up to a whole stem before working out whole supplier bunches.
Keep the buffer and bunch rounding separate.
Your buffer is an intentional allowance for extra flowers. Bunch rounding is the additional stock you buy because your supplier sells fixed quantities. They are different numbers, and the worksheet shows both so you can see why your purchase exceeds the design count.
A larger bloom, a different grade, or a branching stem can change the recipe. Use a flower guide to explore your options, then confirm your own stem count with the design in hand.
A garden rose ordering example.
Suppose you need 15 centerpieces, each with 5 garden roses. You choose a 10% buffer and your supplier sells roses in bunches of 12.

If your entered cost is $3 per stem, those 84 roses cost $252 before shipping or tax. This is an example cost, not a current wholesale quote. The 75 roses in the designs alone would cost $225, which explains why recipe usage and the actual flower purchase are different amounts.
Check the supplier’s unit before you order.
Stems versus bunches. If a 10-stem bunch costs $25, enter a $2.50 cost per stem and a bunch size of 10.
Flower heads versus stems. A spray or branching stem may carry several flowers. Order the supplier’s stem unit and build your recipe around usable stems, not the number of blooms in a photograph.
Pack size versus minimum order. This calculator rounds to one bunch size. Separate case minimums, mixed boxes, supplier minimum spend, or availability constraints need another check.
Matching products. Combine counts only when the variety, color, grade, supplier, and delivery timing can actually share stock. Similar names alone do not make two purchases interchangeable.
Planning more than one event? Add compatible requirements together before rounding up to supplier packs. Rounding each recipe separately can make you buy more bunches than you need. Studio’s purchasing workflow combines the saved event recipes you select.
Once your quantity is clear, use the floral pricing calculator to include supplies, design time, and your materials multiplier in the selling price of the arrangement.
BEFORE THE NEXT STEM
A few practical questions.
How many stems go in a bridal bouquet?+
There is no single count that works for every bouquet. Flower-head size, silhouette, foliage, and the number of branching stems change the recipe. Count the ingredients in a sample bouquet, then scale those counts for repeated designs.
Can I calculate foliage as well as flowers?+
Yes. Use the actual units your supplier sells and the number used in your design. If foliage is sold by weight or variable bunch size, confirm an appropriate unit and usable yield before treating it as a fixed stem count.
What buffer percentage should I use?+
Use an allowance based on your flower quality, handling experience, opening requirements, and supplier reliability. The field starts blank; the 10% in the written example is illustrative rather than a universal recommendation.
Why does the calculator round up twice?+
The first rounding gives you enough whole stems after the buffer. The second gives you enough whole supplier bunches to cover that requirement. The results separate intentional buffer stems from extra stems created by bunch rounding.
Does this order flowers from a wholesaler?+
No. It creates a planning worksheet. Check the final product, color, quantity, availability, delivery date, and price with your supplier before placing an order.
