About Catbird Bracelets
At Catbird, our bracelets range in size from 6 inches to 8.5 inches. Many options are also adjustable, to accommodate a variety of fits. We are here to help you find the right bracelet fit. Our guide helps you measure, layer, and wear with the right size.


How to Measure Your Bracelet Size
Step 1: Find a measuring tape. You will use this to measure your wrist.
Step 2: Locate your wrist bone. You can feel it at the pinky and thumb side of your wrist, where your forearm meets your hand.
Step 3: Wrap the measuring tape around your wrist bone closely.
Wrist Measuring Tip: Keeping your palm open and facing upwards can help make measuring easier.
Step 4: Note down the measurement. This is your wrist measurement.
Step 5: Now convert your wrist measurement to a bracelet measurement. Add approximately ½ an inch to your wrist size for a snug bracelet fit or up to a full 1 inch for a relaxed bracelet fit.
Bracelet Sizing Tip:
To determine whether a snug or loose fit suits you, consider your lifestyle. If you’re active and typically like sleeves to fit closely to avoid catching as you move, you may want a snug fit.If you’re inclined to be more comfortable in flowy outfits, or like your sleeves to have more give, a looser fit may suit you. When in doubt, opt for an adjustable bracelet, so you can customize the fit depending on your mood, activity, our outfit.
No measuring tape?
No problem! Just take a string, follow the steps above, and measure against a ruler. You've found your measurement!

BRACELET SIZING FAQs
Should my bracelet fit loose or snug?
To determine whether a snug or loose bracelet fit suits you, consider your lifestyle. If you’re active and typically like sleeves to fit closely to avoid catching as you move, you may want a bracelet with a more snug fit. If you’re inclined to be more comfortable in flowy outfits, or like your sleeves to have more give, a looser fit work better for you. When in doubt, opt for an adjustable bracelet, so you can customize the fit depending on your mood, activity, our outfit.How should a tennis bracelet fit?
A tennis bracelet should fit snugly but still allow some movement on your wrist. Ideally, you should be able to slide one finger comfortably between the bracelet and your skin. It shouldn't be so tight that it leaves marks or so loose that it risks slipping off. The perfect fit allows for movement while staying securely in place. When measuring your wrist & determining bracelet size for a tennis bracelet, opt for a more snug fit.How should a chain bracelet fit?
A perfectly fitting bracelet should allow for one or two fingers to comfortably fit between the bracelet and your wrist. The bracelet should rest just above your wrist bone without pinching your skin or sliding too far down onto your hand, risking it fall off. A bracelet should fit according to your preferences as a wearer as well. You may prefer a more snug fit, or a looser fit. Refer to our above bracelet sizing guide for step by step instructions on how to determine your bracelet size and wrist measurement.Should I choose an adjustable or fixed length bracelet?
An adjustable bracelet is a great choice for anyone who is unsure of their exact bracelet size, wants to accommodate for a fluctuating bracelet size, may have a bracelet size that needs customization beyond standard fixed bracelet lengths, or who simply wants the flexibility to adjust their bracelet size depending on the occasion, activity, or outfit.Does bracelet size fluctuate with temperature or season?
Yes, your bracelet size can fluctuate due to natural changes in your wrist size. Factors like hydration, temperature, physical activity, and weight changes can cause your wrist to expand or shrink by up to a half-inch throughout the day. Keep daily activities and seasonal fluctuations in mind when determining your bracelet size. Time of day: wrists tend to be about 0.25 inches smaller in the morning and can swell by 0.25 to 0.5 inches by the evening. Activity: Exercise can increase your wrist size by 0.5 to 0.75 inches due to increased blood flow. Weather & Hydration: Heat, humidity, and high sodium intake can cause water retention, making your wrists swell. When in doubt, go for an adjustable bracelet, or add a chain extender.What is an adjustable bracelet?
An adjustable bracelet is a bracelet that can be customized in size within a fixed range. Our adjustable bracelets are made with solid gold or sterling silver, and feature an extra 1.25 - 1.5 inches of chain, that can be secured closed with the bracelet clasp along any length of the chain extender, offering a more customizable fit beyond the standard inch lengths of a fixed length bracelet.
