The color thing
It is worth saying plainly: a large share of "golf gifts for women" content is the men's list with pink products substituted in. Golf equipment is not gendered in any meaningful way. A rangefinder measures distance identically regardless of who holds it, and a golf ball does not know who hit it.
There are two genuine exceptions, and they are both about fit rather than preference: gloves and shoes are made on different lasts and in different size ranges. Everything else on this page is chosen on what it does.
Where the real differences are
Gloves.Women's golf gloves run smaller and are cut differently, and the hand is the same rule as for anyone: a right-handed golfer wears it on the lefthand. If you don't know her size, this is a gift to skip — a badly-fitting glove is worse than no glove. Our glove sizing guide covers how to work it out if you can get a look at one she already owns.
Ball choice.Ball manufacturers publish compression figures, and a lower compression ball suits a slower swing speed. That correlates loosely with gender on average, but it correlates far more strongly with how hard a specific person swings — so the honest advice is the same one we'd give for anyone: if she's newer to golf or doesn't swing hard, a softer ball is the safer pick. Compression explained, without the jargon.
The gifts that land regardless
Accessories are where this gets easy. A leather scorecard holder, a magnetic towel, a set of hat-clip ball markers and a ball stencil are all genuinely useful, all size-free, and none of them requires you to know anything about her game.
At the top of the budget, a rangefinder or a GPS watch is the same excellent gift it is for anyone. The Garmin watch in particular gets picked here because it passes as an everyday watch, which means it gets worn rather than dug out on Saturdays.
If she's new to golf
Beginners lose a lot of balls and worry about holding people up. The most useful things you can buy in that situation are cheap and unglamorous: a soft, forgiving ball, a decent glove, and something for practicing at home where nobody is watching. Our gifts for beginner golfers page goes into that properly.
