Most couples will begin planning a wedding 12-18 months before the big day. This allows you plenty of time to get everything organised, from the big elements like the wedding venue, food and photographer, down to the small details like the cake topper and bridesmaids dresses. However, many couples will also plan well in advance with over 2 years to go before their wedding and others have done it in less than 6 months! It's entirely down to you and your partner, how long you'd like your engagement to be and, of course, the availability of your chosen wedding venue.
