Frequently Asked Questions
For a local Saturday spring wedding, send 236 invitations to fill 200 seats. The reliable range is 223–251. At this scale, the 85% attendance rate is very consistent, and you're unlikely to see more than ±10 people from your midpoint estimate.
Not if you have the right tools. The complexity at 200 guests is in the data management, especially tracking 236 invitations, RSVPs, meal choices, and addresses. iDoTogether automates that layer, so you don't need a planner just to manage who's attending.
On average, 15-20% of invited guests decline a local wedding. For destination weddings, the decline rate jumps to 30-40%. Factors like day of the week, season, and travel distance all affect the final number. Saturday weddings see the highest attendance, while weekday ceremonies can see decline rates as high as 30%.
The average wedding drop-off rate is about 15% for local weddings held on a Saturday. This means if you invite 100 guests, roughly 128 will attend. Destination weddings have a much higher drop-off rate of around 35%, meaning only 98 out of 100 would attend. These are industry averages — your actual numbers will depend on your specific guest demographics.
It depends on your wedding type. For a local Saturday wedding, you can safely invite 15-20% more guests than your venue capacity. For a destination wedding, you may be able to invite 50-55% more. Use the 'Fill My Venue' mode above to find the right invite count for your venue size.
Season plays a meaningful role. Spring and fall weddings tend to see the highest turnout due to comfortable weather and fewer travel conflicts. Summer weddings (especially July/August) can see 3-5% lower attendance due to vacation conflicts. Winter weddings often see 5-8% lower attendance due to weather and holiday scheduling.
Friday weddings perform much closer to Saturday than Sunday does. Many guests are already in a weekend mindset, and taking one day off from work is more manageable than losing a Sunday evening before the work week. Sunday weddings consistently show higher decline rates because guests need to be back at work Monday morning.
The biggest bottleneck is chasing people who ignore paper mail. iDoTogether lets you text each guest a personal link. They tap it, RSVP, and submit their meal choice in under 60 seconds. Couples using our software typically collect 80% of RSVPs within the first week.
Send RSVP requests 6-8 weeks before your wedding date. Follow up with non-responders at the 4-week mark. (Pro-tip: If you use iDoTogether, your dashboard automatically flags exactly who hasn't answered, so you don't have to manually cross-reference a spreadsheet).

Filling a 200 Seat Venue?
A 200 seat venue requires approximately 236 invitations for a local Saturday spring wedding. At this scale, the law of large numbers works in your favor: attendance variance narrows significantly, and the 85% local Saturday rate is highly reliable. The over invitation buffer (236 minus 200) is about 35 extra people, which is exactly the statistical cushion you need. Coordinating 236 invitations across 80–90 households is still meaningful work, but the attendance prediction itself is the most reliable of any size on this list.
To fill 200 seats you need {inviteTarget} invitations across 80–90 households, each requiring address collection, meal choices, and RSVP tracking. iDoTogether handles all of it automatically so you can focus on the parts that actually matter.
