Measuring Tips

Here are some tips to help you order the correct size. If you don't have a measuring tape, no problem! Use a piece of string or ribbon to mark the measurement and then hold it alongside a ruler or yard stick to find the measurement.

Head Circumference

Measure around your head just above your ears angling slightly up across your forehead to get your full head circumference.

Bust

Lift your arms slightly and measure around your body (without a shirt is best), crossing over the fullest part of your chest.

Chest

Lift your arms slightly and measure around your body (without a shirt is best), crossing over the fullest part of your chest.

Waist

Measure around the natural waist, where you normally wear your pants, shorts or skirt.

Waist

Measure around your waist where your pants or shorts usually fall.

Hip

Stand with your heels together and measure around the fullest part of your hips.

Seat

Stand with your heels together and measure around the fullest part of your hips.

Arm Length

With your arm bent at 90 degrees, place your hand on your hip. Measure from the back of your neck to your shoulder, elbow, and wrist.

Foot Length

Lay a ruler or yardstick on the ground and stand with your heel positioned at “zero”. Measure the full foot length from heel to the end of your big toe. If you have a second ruler, its handy to use the second ruler to make sure your heel aligns perpendicular to “zero” and big toe aligns perpendicular to the final foot length measurement

The Story Behind UVSkinz

Guided by her vision, UV Skinz has grown to represent a life full of freedom, peace of mind and sun-filled adventure. Join us in our mission, we’ve got you covered!
