Measure your swing.
Then read the chart.

01 / THE RIGHT NUMBER

Club speed goes in.
Ball speed stays separate.

Driver swing speed means how fast the club head travels just before impact. Ball speed describes the ball immediately after impact. A screen may show both; copy the field labelled club speed or club-head speed. [1] [2]

Keep the unit with the number. 100 mph is about 161 km/h. Entering 161 as mph describes a very different swing. A carry chart cannot correct a mistaken input.

02 / A WAY TO MEASURE

Start with equipment
you can already access.

A lesson, fitting or simulator session can be a practical first measurement. Before booking, ask whether that particular setup reports driver club-head speed and lets you keep the session readings. Trackman describes club speed, ball speed and carry among the data a launch monitor can provide. That does not establish the capabilities of every device. [3]

Use the manufacturer’s setup instructions for the model in front of you. If you record a practice swing without a ball, label it that way and keep it separate from shots hit with a ball.

03 / A USEFUL RECORD

Keep the session,
not only your fastest swing.

Our suggested starting routine: warm up as you normally would, then save a small set of ordinary driver shots rather than only the fastest result. Note obvious mishits instead of quietly deleting them. This is a practical recording suggestion, not a validated testing protocol.

Trackman’s own distance guidance recommends focusing on average carry rather than the longest shot. Keep enough of your session to see what is typical for you. [4]

04 / ESTIMATE VS. YOUR SHOTS

The chart starts a question.
Your shots help answer it.

ClubCarry estimates carry from driver speed and a selected contact level. It does not measure your launch, spin or impact. Two players with a similar swing speed can get different carry: Trackman identifies ball speed, launch angle and spin as factors in reaching potential distance. [5]

Compare like with like. Total distance includes the ball’s final resting position; carry is a separate flight-distance metric. A long roll is not evidence that the carry estimate is low. On uneven ground, check how your device defines carry. [6]

Check the display mode too. Normalized distance models a shot under specified standardized conditions, so it is not the same as an actual-condition reading. Record the setting when comparing sessions. [7]

05 / BEFORE BUYING EQUIPMENT

Choose the measurement
before the product.

If you only need a first baseline, compare access to a session with the cost and practicality of owning a device. For home practice, check the exact model’s club-speed support, indoor and outdoor requirements, ball and space requirements, software costs and return terms.
