How Many Flowers Do You Actually Need for Your DIY Wedding?

Figuring out how many flowers you need for your wedding can feel like a total stab in the dark. Order too few and you're scrambling the week of. Order too many and... well, honestly, I don't think you can ever have too many flowers. You'll find a way to use them - even if that means leaving a bouquet on a neighbor's doorstep to brighten their day. But of course we want to cut down on extra cost as much as we can, so let's get you to a number you feel confident about.

Start with "stems"

In the flower world, we talk about quantities in terms of stems, rather than number of flowers. That's because foliage counts too. A stem of eucalyptus or a few stems of mint plays just as important a role in your finished design as the flowers themselves.

First: map out where you want flowers

Before you can estimate quantities, you need to answer a few questions:

• Where do you want flowers? Guest tables, escort card table, cake, bar, ceremony space?

• For each surface: bud vases, or something arranged in a bowl or compote?

• What personal flowers do you want - bouquets, flower crowns, boutonnieres, corsages?

• Are you doing any kind of installation, like a floral arch?

Once you have a picture of your full floral footprint, you can start doing the math.

The variables that affect your stem count

It's hard to say an exact number of stems needed for an arrangements because lots of factors change the amount of stems you need. For example:

Style. An airy, loose arrangement uses fewer stems and more negative space. A lush, compact arrangement packs in more.

Vessel size. This is a big one. A bud vase needs 3–5 stems. Bowls and compotes with wide openings are actually easier to work with than you'd expect — tuck a ball of chicken wire inside to give yourself control over stem placement (more on that in a future post!). But the wider the mouth, the more stems you'll need to fill it without it looking sparse.

Flower type. Hydrangeas are a great example: one stem of hydrangea takes up the space of several smaller flowers. If your mock-up used hydrangea but your final design won't, you'll need to add stems to compensate.

Two ways to figure out your stem count

Make a mock-up. This is my favorite approach if you don't have a lot of arranging experience. Grab the actual vessel you're planning to use, buy some flowers, and make an arrangement until it looks the way you want. Then count every stem you used - flower by flower, foliage by foliage. That count becomes your flower recipe for that type of arrangement.

Count stems in your inspiration photos. Pull up an arrangement you love and count what you see. How many big round flowers? How many spike flowers? How many little cluster flowers? You don't need to know the names of the flowers - just the counts within shape categories. Don't forget to try an estimate the part of the arrangement you're not seeing. For example, if you're counting stems of a centerpiece arrangement, you're only seeing one side of the arrangement so multiply your count by two for the other side you don't see. For arch or garland inspiration, try estimating flowers per foot, then multiply by however many feet you're covering.

A starting point if you're not sure where to begin

If you're working from scratch with no mock-up, here are some rough benchmarks:

• Bridal bouquet: ~30 stems for an average-sized, full bouquet

• Bridesmaid bouquet: ~20 stems

• Mason jar centerpiece: ~15 stems

These aren't rules - they're a floor. From here, adjust up for more lush arrangements or larger vessels, and down if you're going airier or more minimal.

One last thing: DIYing your wedding flowers is absolutely doable and rewarding.

It takes some planning and a little practice, but you don't need to be a professional florist to make something beautiful. Many people getting married do it every year - and walk away proud of what they made.

If you want to give yourself a real advantage and you're getting married during the local growing season, seek out locally grown flowers. Locally grown stems are magical - freshly cut, full of life, and honestly just gorgeous on their own. When your flowers are that good to begin with, the arranging gets a lot easier. You don't need to fuss as much to make them look special, because they already are.
