World Rugby expands smaller ball trial in women’s game—what changes to expect
smaller ball – World Rugby will trial a size 4.5 ball in elite women’s 15s later this year, aiming to boost offloading and gameplay—while testing concerns about kicking and cost.
World Rugby is set to widen a trial of a smaller match ball in the elite women’s game, with a size 4.5 ball planned for WXV later this year.
The move centers on a specially designed Gilbert ball that is roughly three per cent smaller than the standard size five. but keeps the same weight.. The product has already been tested on the HSBC SVNS series this season. after earlier experiments in age-grade internationals and even club training sessions.
The next phase matters because it shifts the trial from pathways and coaching environments into the spotlight of elite 15-a-side competition.. World Rugby intends to use the WXV setting to gather more concrete data and player feedback in match conditions—exactly where gameplay decisions. skill execution. and tactical patterns tend to be most revealing.
A smaller ball has been a long-running talking point in women’s rugby.. For supporters of the change. the argument is practical: it can make key ball-handling skills feel more accessible. particularly in fast phases where offloads and quick passes decide territory and momentum.. In a high-tempo contest. even small differences in grip and contact can affect whether a player commits to a two-step offload or chooses a safer option.
Katie Shillaker. a captain for Great Britain Sevens during the season. has said she noticed a clearer emphasis on offloading after switching to the four-and-a-half size ball.. Her view is that the benefits show up quickly: catching. passing. and the ability to play the ball into contact—without losing shape—can feel a bit easier.. She also points to how teams adapt defensively when they believe offloads will come.
The trade-off, as some players have warned, is that not every skill is equally affected.. Shillaker suggested kickers may feel the impact more directly. which is a crucial detail for a sport where kicking can swing games in ways that are hard to replace with raw ball-in-hand dominance.. World Rugby’s decision to preserve the ball’s weight appears designed to reduce the risk of a disruptive change to kicking feel. but the trial’s purpose is to test whether that reassurance holds up in elite match play.
That tension—encouraging one part of the game while protecting others—isn’t unique to rugby.. Across sport. equipment tweaks often follow the same logic: align the physical tool with how athletes actually handle it. then watch whether tactics evolve rather than simply flatten.. Cricket and basketball. for example. already standardize smaller balls for women’s competition. reflecting a broader trend toward tailoring playing demands.
There’s also the human side to this debate.. Equipment changes rarely stay “theoretical” for grassroots clubs.. Any system that requires an extra ball type can create logistical friction—ordering. storage. and ensuring the right ball is available for training sessions.. Even if the elite level benefits. the pathway to broader participation can be affected if clubs feel they must absorb new costs to keep up.
So why push ahead now?. Because women’s rugby is increasingly measured by performance quality, not just participation numbers.. Data from a bigger elite trial can help settle arguments that have lingered for years: does the smaller ball meaningfully elevate the style of play. or does it create unintended imbalance?. And if offloading becomes more common. what does that mean for coaching plans—especially around decision-making under pressure and defensive spacing in those 50/50 contact moments?
Looking forward, the bigger question is whether the sport can standardize change without splintering development.. If WXV provides consistent evidence that the ball improves certain skills while keeping kicking intact. the trial could accelerate into wider adoption.. If the concerns outweigh the gains. World Rugby would at least have clearer answers—built from elite match feedback rather than assumptions.
For players, coaches, and fans, the size 4.5 trial at WXV is therefore more than an equipment adjustment. It’s a test of how the women’s game wants to play: faster, more adventurous, and more willing to challenge contact—provided the essentials, like kicking accuracy, are not left behind.
