The order of play at Wimbledon is published the evening before and is read closely by players, broadcasters and spectators. It is the product of several constraints that pull in different directions.
Court capacity is the starting point
Only a handful of courts hold significant crowds, and the early rounds must fit a full draw of singles alongside doubles and junior events into a fixed number of days.
That arithmetic forces most matches onto outside courts, where the schedule is a queue rather than a timetable and each match starts when the previous one finishes.
Show court matches, by contrast, are given start times, which means an overrunning first match delays every match behind it on that court.
Overrun risk shapes the running order
Schedulers place matches likely to finish quickly earlier in the day, because a long opening match compresses everything that follows and can push a headline contest into the evening.
A five-set contest between evenly matched players is therefore rarely first on a show court, even when it is the most attractive match of the day.
The final slot carries the greatest risk of suspension, so it usually goes to a match that would be least damaged by finishing the next afternoon.
Broadcast windows pull in a second direction
Domestic and international broadcasters pay for access to particular hours, and matches involving players from large television markets are worth more inside those windows.
Scheduling accommodates this without letting it dictate, because a tournament that visibly serves one market damages its standing with players from everywhere else.
The compromise is usually to spread notable matches across the day rather than concentrate them, giving every window something worth watching.
Rest and surface wear are tracked
Players who finish late are not scheduled first the following day where it can be avoided, since recovery time is measured from the end of the previous match.
Grass wear is tracked too, and the busiest courts are given lighter days where possible so the baselines survive into the second week in usable condition.
These considerations rarely change which match is chosen, but they frequently change where in the day it lands.
Seeding and etiquette do the rest
Higher seeds and defending champions have traditionally received the principal courts, which functions as a reward and also concentrates the strongest draws where the crowds are.
Doubles, juniors and invitation events are placed to fill gaps rather than to compete with singles, so their scheduling is genuinely subordinate.
The published order therefore encodes a set of judgments about risk and value that the tournament never explains, which is why it is argued about every morning.
