Build the timeline in four passes
Trying to write a wedding day timeline in one pass produces a document that looks complete and falls apart on contact with a photographer. Four passes works better.
| Pass | What you fix | What you need first |
|---|---|---|
| 1. Anchors | Ceremony time, meal time, evening guest arrival, carriages | The venue contract and the licence end time |
| 2. Backwards | Hair and makeup start, photographer arrival, attire, travel | How many people are having hair and makeup — the usual cause of a late start |
| 3. Suppliers | Every arrival and set-up window | Confirmation from each supplier, not your assumption |
| 4. Slack | Fifteen minutes before the ceremony and before the meal | Nothing. This is the pass people skip, and it is the one that saves the day |
Durations that are consistently underestimated
| Task | Realistic duration | Common guess |
|---|---|---|
| Hair and makeup per person | 45–60 minutes | 30 minutes |
| Getting into a wedding dress | 20–30 minutes | 10 minutes |
| Travel between locations | Journey time plus 50% | The satnav estimate |
| Seating guests before the ceremony | 20 minutes for 100 guests | 10 minutes |
| Group photographs | 3 minutes per group | 1 minute |
| Calling guests through to the meal | 15 minutes | 5 minutes |
| Serving a three-course meal | 90 minutes | 60 minutes |
| Speeches | 8–10 minutes each, and always longer than promised | 5 minutes each |
| Room turnaround | 30–45 minutes | Instant |
Add those differences up across a day and the gap is routinely two hours. That is why timelines fail: not one large error, but nine small optimistic ones in the same direction.
The one page every supplier gets
In the final week, send one message to every supplier with the same attachment: the times, the addresses, the on-site contact name and number, and their own arrival window highlighted. Not three versions, not a group chat. One document, one version, sent once.

Common questions
How do you build a wedding day timeline?
In four passes: fix the anchors (ceremony, meal, evening, carriages), work backwards to hair and makeup, add every supplier arrival window, then add fifteen minutes of slack before the ceremony and before the meal.
What is always underestimated in a wedding timeline?
Hair and makeup at 45–60 minutes per person, travel at journey time plus 50%, group photographs at three minutes each, and the room turnaround at 30–45 minutes. Nine small optimistic guesses in the same direction add up to about two hours.
When should you send the timeline to suppliers?
In the final week, as one document to everyone at once, with their own arrival window highlighted and an on-site contact number who is not you.
How much slack should a wedding timeline have?
At least fifteen minutes before the ceremony and fifteen before the meal. Those two buffers absorb almost every ordinary delay.
