Numbers Wedding cost by guest count
How much does a 155 person wedding cost: three budgets for one hundred and fifty-five guests
The same ten vendors, priced three ways, for a wedding of one hundred and fifty-five people. Food is multiplied by 155. The rest is what couples actually paid.
The short answer
Based on The Knot's 2026 vendor prices, a wedding for 155 guests costs about $19,979 at the low end, $33,884 in the middle and $68,152 at the high end, before drinks, invitations and the officiant. Food is the line that belongs to this count: at $70 a head, catering for 155 is $10,850.
At one hundred and fifty-five guests the food and drink lines start to rival the venue. A few extra names look cheap until you multiply them by the caterer's price per head. The national average of $292 a guest would put 155 people at $45,260. That number folds in the venue and the dress, which do not change if you invite ten more. The useful figure is the catering line, and the three columns below.
Three versions of a 155 guest wedding
The Knot's 2026 Real Weddings Study, of 10,474 couples married in 2025, reports each vendor at three levels. The low column is what the bottom quarter of couples paid, the middle is typical of the middle half, and the high column is what the top quarter paid. Catering is per head, so it is multiplied by 155. Cake and rentals are scaled from the study's 100-guest figures. Venue, photographer, dress, DJ, attire and hair stay as reported, because they do not grow with every extra seat.
| Line | Low | Middle | High |
|---|---|---|---|
| Venue | $3,500 | $10,400 | $24,800 |
| Catering, 155 guests | $9,300 | $10,850 | $20,150 |
| Photographer | $1,500 | $2,800 | $4,700 |
| Wedding dress | $1,200 | $2,000 | $3,200 |
| Florist | $1,049 | $2,214 | $5,592 |
| Event rentals | $1,705 | $2,635 | $4,960 |
| DJ | $800 | $1,600 | $2,700 |
| Cake | $465 | $775 | $1,240 |
| Groom's attire | $260 | $310 | $410 |
| Hair and makeup | $200 | $300 | $400 |
| Total | $19,979 | $33,884 | $68,152 |
| Per guest | $129 | $219 | $440 |
The middle column is $219 a guest. The Knot's national average is $292 a guest for 117 people. A larger wedding is usually a little less per head, because those same fixed lines are spread further.
Where the prices come from
These prices are based on The Knot's 2026 vendor data, then scaled to 155 guests where a line grows with the list.
- Catering. The Knot's low, typical and high prices per head ($60, $70 and $130), times 155.
- Cake and rentals. The study's 100-guest amounts, scaled by 155 / 100.
- Florist. The study's amounts, scaled gently (70 percent of the 100-guest figure plus 30 percent times 155 / 100), because flowers grow with the room but not one-for-one with seats.
- Venue, photographer, dress, DJ, attire, hair. As reported in the study. A room for 155 can cost less or more than the typical venue line. Use the column that matches the room you are looking at.
- Drinks, invitations, officiant. Not in the ten lines. Zola's 2026 survey puts bar service at about $47 a guest (from its $5,542 average across 117 guests), the invitation suite at $500 for that average wedding, and the officiant at $325.
With a bar, invitations and an officiant at those figures, the middle column comes to $42,156. The bar alone is $7,285.
To count bottles rather than a package, see how much alcohol you need. For the method behind a 100 guest version of this table, see the 100 person wedding cost guide.
A hotel package at 155 guests
A couple taking a hotel or country-club package, where the room is expensive and the rentals line almost disappears. Putting those choices on this count:
| Line | Column | Amount |
|---|---|---|
| Venue | high | $24,800 |
| Catering | mid | $10,850 |
| Photographer | low | $1,500 |
| Rentals | low | $1,705 |
| Everything else | middle | $7,199 |
| Total | $46,054 |
That is $12,170 more than the all-middle column of $33,884. The trade is the same one most couples make: spend on two priorities, and pick the venue column by what the room includes. Our guide to what a wedding venue costs compares the three ways venues price.

What ten guests more or less changes
Ten more guests at the middle catering price is $700 of food. That is not ten times $219, which would be $2,190 and would pretend the photographer comes along. Add drinks at $47 a head and ten more people are about $1,170 before tax and service. If you are cutting instead, the guide to cutting a guest list has a fair method.
RSVPify's 2019 figures found 83 percent of invited guests said yes. To seat about 155, invite around 187. Our guide to how many people to invite works through that rate.
