It probably comes down to the International Match Calendar by FIFA as well.
Eg, In the 2025-26 season (including the offseasons before and after - so this includes the current international window), this is the comparison for Men's and Women's:
Men's have 12 matchdays, plus the FIFA World Cup for those that qualify, and a window specifically for the CONCACAF Gold Cup, and the CAF African Cup of Nations. 2 of those 12 matches are specifically earmarked as 'Pre-World Cup Friendlies'
Women's have a bit more of a complicated calendar.
Firstly, it's split into:
- Type I - Monday to Tuesday night (2 days / 1 match?)
- Type II - Monday to Wednesday night (3 days / 1 match?)
- Type III - Monday to Saturday night of the following week (13 days, probably 3 or 4 matches?)
I'm not sure exactly how many matches each 'Type' has with the above - because the current window is listed as 'Type I'.
But in 2026, this is going to change to:
- Type 8 - Monday to Tuesday night of the following week (2 matches)
- Type II - Monday to Saturday night of the following week (3 matches)
I have no idea where I'm going with this - I'm on a random Saturday night rabbithole.
But there's a window now, and another one at the end of the month, so depending on the confederation, that's 4-8 matches apparently.
Then UEFA, OFC, CONMEBOL and CAF all have their continental cups across July and August. 5 more windows between August and June/July totalling 12-13 matches (depending on the confederation and scheduling), plus a window for the AFC Asian Cup, and then also a 'Blocked Period' from late February-early April 2026 (Final competition of the championships for women’s “A” representative teams of the confederations (including release period))"
Either way, not counting the tournaments, and blocked periods, that's still at least 16 matches - so it's perfectly reasonable for each confederation to have their own WCQ, and continental qualifying structures. Although there's also the Olympics that's still an open age tournament, so that's essentially a second World Cup for women.
UEFA, Oceania and CONMEBOL do currently have their own separate World Cup and Continental Cup qualifiers
AFC, CAF and CONCACAF do not (eg, the Continental Cup have their own qualifiers, and the Continental Cups themselves serve as the World Cup Qualifiers for the region).
For the Olympics, AFC, OFC, CAF have their own separate qualifiers, and UEFA use the Women’s Nations League as the qualifiers (so is still separate from the World Cup/Euros qualifying).
