Your wedding guest list is not a single spreadsheet column—it is a negotiation between venue capacity, family expectations, and the budget you actually have. Start with a template that separates who must be there from who you would love to invite if seats appear, and you avoid the painful rewrite when the caterer quotes per head.
This guide walks through tier A, B, and C lists, plus-one rules that stay fair, and capacity maths that keeps catering honest. Pair it with a digital RSVP workflow so every yes or no updates your numbers automatically.
Start with capacity, not names
Before you add a single cousin, confirm seated capacity with your venue—not the brochure headline, but fire regulations, dance floor layout, and any room flip between ceremony and reception. Split two numbers: your comfortable target (where guests can move and eat without elbow wars) and your absolute maximum.
Write both figures at the top of your list. Every tier decision flows from them. If your venue seats 90 comfortably and 110 at a squeeze, plan catering and rentals for 90 until Wave B invites prove you have genuine declines.
Tier A, B, and C: who goes where
Tier A is non-negotiable for you both: parents, siblings, wedding party, and the handful of people whose absence would feel wrong on the day. These names receive save-the-dates first and the earliest RSVP deadline.
Tier B holds close friends, extended family you see regularly, and colleagues you genuinely want at the table—not everyone who shares your office Slack. Tier B invites go out once Tier A RSVPs are mostly in, or on a fixed date you communicate kindly to everyone waiting.
Tier C is your overflow: lovely people you would host if chairs appear. Many couples never send Tier C at all; others activate it only when declines exceed ten seats. The point is having a plan before Aunt Linda asks why her neighbour got an invite and her book club did not.
For the emotional side of trimming, see our guide on cutting your guest list without drama. Tiers work best when the rules are shared early between you and your families.
Plus-one rules that stay consistent
Nothing erodes goodwill faster than random plus-ones. Decide your rule once—married and engaged partners, cohabiting couples of six months, wedding party only—and apply it across tiers. Exceptions happen; document them beside the guest record so you remember why in three months.
If you are limiting partners, use clear wording on invitations. Our no plus-one templates help you say it kindly. For child-free celebrations, pair tiers with adults-only wording so expectations match your capacity maths from the start.
Count plus-ones in your headcount from day one. A list of 80 names with loose plus-one assumptions can become 110 bodies when RSVPs land—and that is when catering quotes jump.
Capacity maths every couple should do
Multiply confirmed guests (including plus-ones and children) by your per-head catering figure. Add 5–10% buffer for vendor meals, last-minute corrections, and the cousin who swears they declined then arrives with a partner. Compare the total to your catering line in the budget; if it exceeds plan, trim Tier B before you print invites.
Guest count also drives chair hire, favours, alcohol, and stationery. Our cost-per-guest guide explains how each RSVP shifts spend. Treat headcount as a live number, not a cell you set once in January.
Children, dietary notes, and seating groups
Decide early whether children are invited to the full day, evening only, or not at all. That choice affects headcount, noise, and menu pricing. Tag families in your list so meal counts stay honest when a parent RSVPs for two adults and a toddler who needs a high chair—not a three-course plate.
Capture dietary requirements when guests reply, not when the caterer chases you in the final week. Vegan, halal, coeliac, and allergy notes belong beside each name so your kitchen summary exports cleanly. See our dietary requirements guide for a workflow that keeps chefs and guests aligned.
Group guests by table affinity before you assign seats—school friends together, feuding uncles apart. Tier tags help here: Tier A family names often anchor tables while Tier B friends fill surrounding seats once numbers firm up.
Track tiers and RSVPs in one place
Spreadsheets fracture when one partner edits on a phone and the other on a laptop. WedCheese keeps your guest list, tier tags, plus-one flags, dietary notes, and RSVP status in one app—linked to your budget so a surge of acceptances updates catering projections without manual formulae.
Send personal RSVP links so guests reply on their phone without creating an account. You see acceptances, declines, and meal choices as they arrive, which makes Wave B timing straightforward: open the next tier when your seated count plus buffer still fits the room.
Export a headcount summary before every caterer call. When your mum asks how many cousins are coming, you answer from live data—not a guess from a notebook last updated in March.
Build Tier A this week, agree plus-one rules with your partner, and lock capacity before save-the-dates go out. A calm list early saves the budget arguments later.
