golf ball marker

Typical sizes include: liners — inner diameter about 41 mm (1.61 in) with an overall liner size of roughly 66 × 45 × 30 mm (2.6 × 1.77 × 1.18 in); round transparent position markers — about 24 × 8 mm (0.94 × 0.31 in diameter × thickness); removable markers used with divot tools — commonly about 1 in (25.4 mm) diameter.

Liners are used to draw alignment lines on a golf ball to help with swing or putting alignment. Ball position markers are placed on the green to mark a ball’s spot so it can be lifted and replaced accurately.

Place the liner over the golf ball (aligning it properly), then use a marker pen to draw the alignment line through the liner’s guide. Also check your golf ball’s diameter before ordering liners to ensure a proper fit.

Durability depends on material and construction: ABS plastic is described as durable and impact-resistant; solid metal construction (cast or steel) is sturdier; and protective finishes such as durable enamel paint can help preserve the marker’s surface.

Some ball markers are removable magnetic markers designed to attach securely to divot tools, clips, hats, or belts. Others are made for strong magnetic compatibility with dedicated mounts.

Combined accessories typically pair a steel divot-repair tool with a removable magnetic ball marker. Many designs also include an indented clip or magnetic backing for attaching the accessory to a belt, hat, or bag.

Store plastic position markers at normal room temperature when not in use to help maintain them. Liners also recommend checking your golf ball’s diameter before ordering to ensure the liner will fit correctly.
