Only 13% of engaged couples say they are splitting wedding planning equally. The rest of the work lands almost entirely on one partner, and according to Zola’s 2026 First Look Report, 84% of women reported carrying most of that load themselves. This isn’t happening only in relationships either partner would describe as old-fashioned or unbalanced. It’s happening inside partnerships that, by nearly every other measure, present as equal. The gap between how equal a relationship feels day to day and how equal the actual to-do list gets divided may be the most stubborn number in modern wedding planning.
The Numbers Behind the To-Do List
Zola’s data, drawn from more than 11,500 couples in what the company calls its largest survey ever, found that just 13% of respondents describe wedding planning as a 50/50 split, per the report. The remaining 87% report an uneven division, and among heterosexual couples specifically, brides say they’re the ones absorbing 84% of that unevenness. Vendor calls, seating charts, timeline spreadsheets, dress fittings, and the hundred small decisions in between routinely default to one person’s inbox, regardless of how either partner would describe the health of the relationship itself.
Even Same-Sex Couples Split It Unevenly
What makes the pattern harder to write off as simple gender conditioning is that it shows up even where gender roles offer no obvious script. Among same-sex couples surveyed, only 29% report a 50/50 planning split, according to Zola’s findings. That means the imbalance isn’t purely about husbands opting out because society expects it. Something about wedding planning itself — its sheer volume of micro-decisions, its emotional stakes, its social visibility — tends to concentrate onto whichever partner is more willing to hold it, in nearly every kind of couple.
Why She’s Doing It, According to the Couples Themselves
Zola asked couples why the work landed the way it did, and the answers reveal how normalized the imbalance has become. Sixty percent pointed to cultural expectations, describing the arrangement as simply “the way it is.” At the same time, 93% of primary planners said they’re more detail-oriented than their partner, and 83% said they genuinely enjoy planning more. In other words, couples aren’t necessarily unhappy with who’s doing the work — they’ve built a narrative around it that makes an unequal split feel like a personality trait rather than an imbalance worth renegotiating.
The Mental Load Has a Name, and Researchers Are Measuring It
Wedding planning didn’t invent this dynamic; it just puts it under a magnifying glass for a few intense months. A 2024 study in the Journal of Marriage and Family, led by researchers at the University of Bath and the University of Melbourne, surveyed 3,000 U.S. parents and found mothers handled 71% of household cognitive labor overall, compared with 45% for fathers — the invisible noticing, anticipating, and coordinating that never shows up as a chore on a list. The researchers also found fathers routinely overestimated their own contributions, believing the split was closer to equal than their partners experienced it to be. That mismatch in perception is almost identical to what Zola documented among engaged couples: both partners can sincerely believe their relationship is equal while one of them is quietly running the entire operation.
The same study distinguished between two kinds of labor: core, recurring tasks like daily coordination, and episodic, one-off tasks like planning a big purchase or an event. Fathers actually did more of the episodic work, taking on 65% of it compared with 53% for mothers. A wedding, ironically, is the kind of large, one-time, highly visible project where partners are statistically most likely to show up and help — which may be exactly why couples walk away from planning it feeling like their relationship is balanced overall, even while the day-to-day share stays lopsided in the other direction.
What an Equal Relationship Actually Requires
None of this means the couples in Zola’s survey are dishonest about their relationships. It means equality in a partnership and equality in a project plan are two different things that don’t automatically travel together. A couple can share values, split rent evenly, and genuinely respect each other as equals while the wedding binder — like the mental load research suggests happens with laundry, school forms, and pediatrician appointments — still ends up belonging to just one of them. Recognizing that gap, rather than assuming a happy relationship rules it out, is the first step couples describe when they actually manage to close it.
Zola’s own numbers hint at what that looks like in practice: same-sex couples, freed from a default script about who “naturally” handles the details, still land closer to equal than opposite-sex couples do, but they don’t land at 50/50 either without deliberately dividing tasks by preference and bandwidth rather than habit. That’s the harder, less romantic work behind the seating chart — not just picking a venue together, but periodically asking who actually opened the vendor emails this week, and whether that person is doing it because they want to or because, somewhere along the way, it just became theirs.
