Frequently Asked Questions

For a local Saturday spring wedding, expect 118–138 attendees out of 150 invited. The midpoint is 128. Plan catering for 135 to stay safe on food and seating.

Plan food and seating for 135 guests when expecting 128. The extra seats cover vendors who need to eat, last minute RSVPs, and attendance that runs above the midpoint estimate. At typical $75–$120 per plate, ordering extra for 135 instead of 128 costs roughly $225–$360, which is worth it compared with running short.

Use iDoTogether's personal links. Each household gets their own URL, and your dashboard tracks every response in real time. You can see who's pending, send bulk reminders, and share the dashboard with your partner, all without maintaining a spreadsheet.

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).

Planning a 150 Person Wedding?

150 guests is a large wedding by US standards, and you'll experience the full complexity of coordinating households across different family networks, friend groups, and work circles. For a local Saturday spring wedding, expect 128 attendees and 22 declines. Your safe catering buffer is 135. At this size, the cost of RSVP mismanagement is real: if just 10% of guests (15 people) fail to respond, you risk over ordering by $600–$900 at typical per plate costs. Most couples at this size report that RSVP deadline enforcement is the single most stressful part of wedding planning.

A 150 person wedding means at least 35 missing RSVPs in the week before your deadline. Let iDoTogether's smart RSVP system handle it with real time tracking, automatic reminders, and a dashboard that shows who's missing at a glance.
