What Quantity Do I Need?

One of the biggest questions we get from customers is '"What quantity do I need?", so below are some top tips to consider before making your petal purchase.

How we measure & quantity per litre

Firstly, we measure petals in litres and cups, which is standard practice across the petal industry. This is because weight can vary depending on moisture levels in the petals and so volume is a more accurate way of measuring.

We use standard kitchen measuring cups and a litre jug to measure the petals. We fill these to the top with petals when measuring and always ensure the right amount is included in each bag. 

There are 5 cups of Rose Petals in every litre, which gives approximately 5-7 handfuls of petals. 

There are 5 cups of Delphinium/ Hydrangea in every litre also but hydrangea 1 litre of Hydrangea or Delphinium will give approximately 10 handfuls of petals. 

The petals are then packaged tightly in recyclable plastic bags to keep them safe from moisture and make them easy to transport. When they arrive the package may appear deceptively small but will contain the right amount. Once you start measuring them out, or separating them and fluffing them up you will see it's the right volume.

What quantity will I need for... ?


When it comes to confetti you can choose between Rose Petals, Hydrangea and Delphinium. The Rose Petals are larger and more dramatic in photographs, while the smaller, lighter Delphinium petals give you more handfuls per litre and appear more subtle in photographs.

We recommend at least 4 litres of petals to get a good photographic shot of the confetti toss. The more confetti available, the more chances your photographer will have of getting the perfect shot. 

You can work out how much you need by multiplying the amount of guests you want to take part in a confetti toss x 1 cup/handful per person for Rose Petals, or  x1/2 cup/handful per person for Hydrangea and Delphinium.

For example, for 100 guests taking part in a confetti toss you would need;

- 100 cups/ 20 litres of Rose Petals

- 50 cups/ 10 litres of Hydrangea or Delphinium Petals

Please note that in larger wedding parties all guests may not take part in the confetti toss.

Each of our 4x6 inch organza bags is ideal for holding 1 cup of Rose Petals or half a cup of Hydrangea or Delphinium.

We recommend Rose Petals for the ideal proposal petal.

5 Litres (25 handfuls/cups of Rose Petals) is the most popular size when it comes to proposals, although 2 litres would give you 10 cups to decorate a table, bath or to add a few handfuls onto the floor or a bed.

2 litres should be enough to write 'I Love You' or 'Marry Me' in 20cm high lettering using Rose Petals.

For heavier coverage on a floor or bed, or to create a pathway of petals we would recommend at least 5-10 litres of Rose Petals. 

For a real WOW factor you could go for 20 litres or more.

Other Uses

Walkway or Aisle: 1-1.5 cups per square foot for light coverage, 3 cups per square foot for medium coverage, 5 cups per square foot for heavy coverage

For creating heavy petal decoration at a wedding we recommend at least 20 litres, with which you can create a pathway and possibly have petals left over for confetti or table decoration.

Flower Girl's Basket: 6 cups for a small basket, 12 cups for a large basket

Table Decoration:  2-4 cups to decorate the centre of a standard circular table (60")
