Should UEFA Loosen Its Strict Plain Kit Back Rules?
Aug 3, 2026, by Chris
- UEFA's Strict Kit Regulations: UEFA mandates plain back panels on patterned jerseys in European competitions, citing referee visibility and broadcast clarity as reasons, which affects teams with striped or hooped kits.
- Alternative Approaches to Kit Clarity: Competitions like Brazil's Brasileirão do not enforce plain back requirements, successfully maintaining number and name legibility on continuously patterned kits through the use of thick borders and contrasting outline fonts.
- The Delta L Rule and Pinstripe Classification: UEFA utilizes a Delta L color contrast metric (greater than 25) to determine if a patterned kit requires a solid back, and considers pinstripes wider than 2mm as 'striped shirts,' making them subject to these contrast restrictions, as exemplified by the Rangers kit.
UEFA's strict equipment regulations have long been a source of debate among football shirt enthusiasts. Under UEFA rules, jerseys worn in European competitions must feature a designated, high-contrast "number zone," which forces teams with striped, hooped, or patterned kits - such as Atlético, PSG. Juventus, and Newcastle United - to have plain back panels. UEFA maintains that these solid blocks are essential for referee visibility and broadcast clarity, but this can be put in question.
Are Plain Kit Backs Really Needed?
In contrast, competitions such as Brazil's Brasileirão do not enforce a plain back requirement, letting teams have striped designs that continue seamlessly across the back. By using thick borders and contrasting outline fonts, player names and numbers remain legible over complex stripes, demonstrating that a giant blank box is not strictly necessary for clarity.
UEFA measures contrast in the Number Zone using a scientific color contrast metric known as Delta L:
- The Delta L Rule: If the alternating colors on the back of a jersey differ in lightness value by a Delta L score greater than 25 ($\\Delta L > 25$), UEFA considers the pattern too high-contrast for legible numbers and mandates a solid single-color box or patch.
A prime example of UEFA's kit rules is the Rangers 26-27 home kit, which has a solid back panel despite having only pinstripes. Under Section 8.06 of the UEFA Equipment Regulations, shirts featuring thin vertical lines (pinstripes) that do not exceed 2 mm in width and are spaced at least 5 cm apart do not count as "striped shirts." Because they aren't classified as full stripes, they are not subject to standard striped-shirt contrast restrictions. Rangers' pinstripes are apparently wider than 2 mm and therefore counted as striped.
With modern high-definition broadcasting, UEFA's rigid plain back rules feel increasingly outdated. Relaxing the regulation to allow continuous patterns - provided numbers have sufficient (outline) contrast - would eliminate awkward design compromises.

The Woltemade Effect: Juventus Squad Follows Striker With Major Long-Sleeve Switch
Nick Woltemade's arrival at Juventus has sparked an unexpected kit trend in Turin. After the German forward made headlines by debuting a long-sleeved home shirt against AC Milan—becoming the first Bianconeri outfield player in over 12 years to wear an official long-sleeve match kit—his teammates are now following in his footsteps.
The trend reached new heights in Juventus's recent European clash against NEC, where six players took the pitch in long sleeves. Alongside Woltemade, starters Weston McKennie, Douglas Luiz, and Pape Matar Sarr all lined up with full-length sleeves, while substitutes Randal Kolo Muani and Teun Koopmeiners also sported the look off the bench. Interestingly, Douglas Luiz demonstrated that switching to the classic silhouette takes some getting used to, as the Brazilian midfielder changed back into a short-sleeved jersey for the second half.
The sudden revival of long sleeves on the pitch is made possible by Adidas reintroducing authentic long-sleeved player shirts for the 26-27 season. For more than a decade, outfield players at Juventus and across Europe were generally restricted to short-sleeve kits paired with compression baselayers.
With Woltemade leading the charge and half of the Juventus outfield lineup already embracing the design, the retro aesthetic looks poised to spread even further across Serie A this season.
