How far in advance should you start planning a wedding?

Most wedding planners recommend starting 12-18 months before your desired wedding date. This gives you the best selection of venues and vendors. However, it is entirely possible to plan a beautiful wedding in 6-9 months if you are flexible on dates and venue options.

What is the most important thing to book first for a wedding?

Your venue should be booked first because it determines your wedding date, guest capacity, and overall style. Once the venue is secured, book your photographer and videographer next as the best ones book 12+ months in advance.

How much does it cost to plan a wedding yourself vs hiring a planner?

A professional wedding planner typically costs $2,000-$5,000 for day-of coordination or $5,000-$15,000 for full-service planning. While this is an additional expense, planners often save couples 10-20% on vendor costs through industry relationships and negotiation experience.

What are the most commonly forgotten wedding planning tasks?

Frequently overlooked tasks include: marriage license application, vendor meal arrangements, transportation for guests, tipping budget for vendors, wedding party gifts, day-of emergency kit, and arranging for someone to return rentals the day after the wedding.
