Wedding Do's and Don'ts
The practical version: what experienced couples and planners do — and the avoidable mistakes they warn everyone else about — organised by the part of planning you are working on.
Budget
✓ Do
- Set the total first, then split it by category before you book anything.
- Keep a real buffer — around 5–10% — for the costs nobody quotes up front.
- Get every quote in writing with tax, service charges and delivery included.
- Spend first on what guests actually experience: food, drinks, music and comfort.
× Don't
- Do not book a venue that eats the whole budget before catering is priced.
- Do not forget tax, service charges, gratuities and overtime in vendor quotes.
- Do not assume DIY is cheaper until you have priced materials, tools and your time.
- Do not spend the buffer early on upgrades; it exists for surprises.

Guests & RSVPs
✓ Do
- Draft an A-list and a B-list so the numbers stay honest as replies arrive.
- Estimate attendance realistically — planners often work with roughly 80–85%.
- Collect addresses and dietary needs while you collect RSVPs.
- Set the RSVP deadline at least a week before your caterer needs final numbers.
× Don't
- Do not invite beyond the venue's comfortable capacity and hope people decline.
- Do not promise plus-ones before you know your totals.
- Do not seat your seating chart before the RSVP deadline; use the planner and adjust.
- Do not chase late RSVPs with stress — send one friendly reminder, then plan on your best number.

Drinks
✓ Do
- Plan on roughly one drink per guest per hour, with extra in the first hour.
- Always provide water and appealing non-alcoholic drinks, not just soda.
- Order about a pound of ice per guest — it is the item weddings run out of most.
- Ask stores about returning unopened cases before you buy.
× Don't
- Do not rely on a single signature cocktail as the whole bar.
- Do not forget the toast: champagne is counted separately from dinner wine.
- Do not under-order ice to save money; warm drinks end parties early.
- Do not ignore venue rules on outside alcohol, corkage and licensed bartenders.

Food & Cake
✓ Do
- Serve appetizers during photos so guests are fed while you are busy.
- Confirm dietary requirements with the final headcount, not the first estimate.
- Feed your vendors — agree who, when and what in writing.
- Time speeches so hot food is not sitting while everyone talks.
× Don't
- Do not offer only one protein if you can avoid it; guests' needs vary.
- Do not skip a late-night snack at a long party — dancing burns dinner fast.
- Do not guess cake servings from the cake's size; use a serving chart.
- Do not forget the cake-cutting time in the evening schedule.

Timeline
✓ Do
- Build the day backwards from the send-off or venue curfew.
- Add buffer around travel, photos and outfit changes — they always expand.
- Share one final timeline with every vendor and the wedding party.
- Plan portraits around the light, especially in autumn and winter.
× Don't
- Do not pack hair and makeup back-to-back with no slack for one late arrival.
- Do not disappear for photos for hours; guests notice an empty party.
- Do not let speeches run open-ended — agree a number and a rough length.
- Do not leave setup and pack-down unowned; name a person for both.

Vendors
✓ Do
- Read contracts for cancellation, rescheduling and what is actually included.
- Confirm arrival, load-in and power needs a week before the day.
- Keep one contact sheet with every vendor's mobile number.
- Pay by milestones in the contract, and keep receipts with the booking.
× Don't
- Do not pay in full long before the event without a contract that protects you.
- Do not book from styled photos alone — ask for full galleries or full event examples.
- Do not assume a friend helping out needs no plan; agree times and tasks kindly, in writing.
- Do not skip the final-week check-in because everything 'seems fine'.

If you only remember five
1. Budget before bookings. 2. Guest count before venue. 3. Ice and water before fancy drinks. 4. Buffers in the timeline before perfect timing. 5. Everything important in writing. The rest of wedding planning is decoration — these five are structure.
Frequently asked questions
Are these wedding do's and don'ts strict rules?
No. They are the patterns that show up again and again in real wedding planning. Your culture, venue and family come first — use this guide to spot avoidable problems, not to plan a wedding that does not feel like yours.
What is the most common wedding planning mistake?
Booking in the wrong order: venue and vendors before the budget and guest count are settled. Almost every expensive problem — capacity, catering minimums, drink quantities — traces back to those first two numbers.
How far ahead should we start planning?
Twelve months is comfortable for popular venues, but weddings are planned in far less time every week. Start with budget and guest list, then venue, then the vendors who can only do one wedding a day.
What should we do first after getting engaged?
Talk money and guest numbers before anything is booked. Then set the budget split, draft the guest list and book the venue — WedCalc's budget calculator, guest list planner and checklist are built in exactly that order.
