Outdoor balls (like Dura Fast 40 and Franklin X-40) feature 40 small precision-drilled holes to penetrate wind shears with heavy 26-gram weights. Indoor balls feature 26 larger holes, allowing the ball to compress and grip smooth indoor gym wood or polished concrete without skidding.","intentTags":["equipment-physics-gear","indoor","knowledge","standards"],"searchKeywords":["what are the structural differences between indoor and outdoor pickleballs?","indoor vs outdoor ball specifications","equipment physics gear"],"facilityTags":["testing-lab","regulation-court"],"serviceTags":["equipment-standards","player-ratings"],"environmentTags":["indoor","outdoor"],"structured":{"categoryId":"equipment-physics-gear","topicIndex":5,"verifiedYear":2026},"lastVerified":"2026-09-20","canonicalUrl":"https://dink-digest.com/knowledge/indoor-vs-outdoor-ball-specifications"},"discovery":{"canonicalUrl":"https://dink-digest.com/knowledge/indoor-vs-outdoor-ball-specifications","hubUrl":"https://dink-digest.com/knowledge","categoryArticlesUrl":"https://dink-digest.com/api/knowledge?category=equipment-physics-gear"}}
