TL;DR: A 25-guest wedding in San Antonio typically runs $8,500 – $22,000, with most couples landing around $13,000 – $15,000. Intimate local venues (Pearl District, Hill Country, downtown Riverwalk) plus seated dinner catering drive the bulk of spend — expect roughly $400 – $700 per guest all-in.

Useful summary

A 25-person wedding isn't just a scaled-down big wedding — the math works differently. With this headcount you can usually:

• Book a restaurant buyout, estate, or boutique venue instead of a ballroom.
• Afford a plated dinner without the per-head cost spiraling.
• Skip or shrink line items that only matter at scale (full band, large floral installs, elaborate transportation).
• Put more budget per guest into the experience (better food, better wine, better photography).

What doesn't shrink with guest count: photography, officiant, attire, planner fees, and rings. Those are close to fixed costs, so they take up a bigger share of a small-wedding budget.

Variable data table

Realistic San Antonio ranges for 25 guests, by tier:

Per-guest math: roughly $340 (lean) / $560 (mid) / $880 (elevated) per person. Small weddings always have a higher per-head cost because fixed expenses spread over fewer people.

Local context

San Antonio is one of the more affordable major Texas wedding markets — generally 15 – 25% cheaper than Austin and slightly under Houston for comparable venues. A few things to know:

• Venue styles that work well at 25 guests: Pearl District restaurant buyouts (Hotel Emma, Cured, Supper), Riverwalk hotel patios, Hill Country bed-and-breakfasts (Boerne, Bulverde, Fredericksburg within an hour), historic McNay or Southtown courtyards, and King William District private homes.
• Season matters a lot. April – May and October – early November are peak (and priciest). July – August is cheap but brutal — if you go outdoor, you need shade, fans, and a 4 pm-or-later start. January and February are the strongest value months with mild weather.
• Catering floor: Expect a minimum of $75 – $95 per person for a plated dinner with one drink tier at a reputable local caterer (Don Strange, Rosemary's, The RK Group). BBQ or taco-bar formats can drop that to $45 – $60 per person.
• Tax + service: Bexar County sales tax is 8.25%, and most venues/caterers add an 18 – 22% service charge. Budget a 25 – 30% uplift on every food-and-beverage quote.
• Out-of-town guests: Many 25-person weddings here include a destination feel. Room blocks on the Riverwalk run $140 – $220/night; Hill Country inns run $180 – $350.

FAQ

What's the minimum realistic budget for a 25-guest wedding in San Antonio?

Around $7,500 – $8,500 if you use a restaurant's private room, skip formal florals, do a DJ-free playlist, and keep photography to 4 hours. Below $7,000 you're usually at a courthouse-plus-dinner format, which is a valid choice but a different event.

How much should I budget per guest for catering at a San Antonio wedding?

Plan on $75 – $130 per person for food and non-alcoholic beverage at a reputable caterer, before tax and service. Full open bar adds $35 – $60 per person for a four-hour event; beer and wine only adds $18 – $28.

Is it cheaper to do a 25-guest wedding at a restaurant or a traditional venue?

At this guest count, restaurant buyouts are almost always cheaper than full-service wedding venues. You skip rental minimums, outside catering fees, and most equipment rentals — typical savings run $2,500 – $5,000 versus a ballroom at the same tier.

Do I need a wedding planner for only 25 guests?

A full planner is rarely necessary at this size, but a day-of coordinator ($800 – $1,500 in San Antonio) is almost always worth it. They handle vendor timing, setup, and family questions so you're not running your own event.

What does photography cost for a small San Antonio wedding?

A 4 – 6 hour package from an established local photographer runs $2,200 – $3,800. Newer photographers or associates at bigger studios start around $1,500. Photo is the category where small weddings get the best value — the coverage is the same whether you have 25 or 150 guests.

Can I legally have the ceremony and reception at the same venue in San Antonio?

Yes, and most 25-guest venues (restaurants, estates, Hill Country inns) are set up for exactly this. Texas requires a marriage license from any county clerk (Bexar County fee is $83), a 72-hour waiting period, and a registered officiant — no venue-specific permits needed.

When should I book vendors for a small San Antonio wedding?

Photography and Hill Country venues go 9 – 12 months out for peak season (spring/fall). Restaurants, officiants, florists, and DJs are typically bookable 4 – 6 months out. Off-peak (summer, January, February) you can compress that timeline by half.
