How many guests will actually use the photo booth?

On average, 70-80% of guests use a photo booth at least once. Many return for multiple visits. Younger crowds and wedding guests tend to have higher usage rates (85%+). For shorter events, participation drops to around 60%.

How big should the backdrop be?

The backdrop should be at least 200cm wide to fit groups of 3-4 people. For larger groups, go to 250-300cm. Height should be at least 200cm. Fabric or sequin backdrops work well. Flower walls are popular but more expensive.

How many props do I need?

Plan for at least 20-30 props for a medium event. Include a mix of hats, glasses, moustaches on sticks, speech bubbles, and themed items. Replace broken or worn props during the event. Sturdy props on wooden sticks last longer than flimsy ones.

How We Calculate This

Print Calculation

Participants = Guests x Participation rate

Total visits = Participants x Average visits per person

Total prints = Total visits x Prints per visit

Strip prints (2x6 inch) fit more per paper roll than 4x6 prints. The calculator estimates paper rolls, ink cartridges and backdrop dimensions.
