FAQ
Length and Cup Compatibility
What length is the wristraw straw?
Two lengths: 20.6 cm (8.1") and 23.8 cm (9.4"). For reference, the industry standard for a reusable straw is about 22 cm, so the longer one sits above it and the shorter one is built for everyday glasses and cans rather than oversized tumblers. This is the length of the straw itself, not the size of the band, which is a separate measurement handled by the silicone wrap's flexible fit rather than a numbered size chart.
Will it reach the bottom of my Stanley or large tumbler?
Usually it does not, and that turns out not to matter. Large tumblers are wide and short rather than tall, and their lids hold the straw in place, so the straw sits at drinking height instead of resting on the bottom. If you have ever used the plastic straw that came with a 40 oz tumbler, you have already noticed it does not touch the bottom either; there is usually an inch or two of clearance built into the design. What determines whether a straw works in a cup is whether it clears the lid opening and stays put once it's in, not whether it reaches the floor of it.
What length should a reusable straw be?
For everyday glasses, cans, and takeaway cups, anything from 19 cm up works comfortably. For tall tumblers and travel mugs with lids, look for 22 cm or more, since a shorter straw can end up too far below the rim to reach with your mouth. Longer is not automatically better across the board: a straw that overshoots a normal glass is awkward to drink from, tips more easily, and sticks out far enough to catch on things in a bag or a car door.
Which length should I choose if I only buy one?
Think about what's usually in your hand, not what's in the cupboard once a year. If most of your drinking happens from a regular glass, a can, or a coffee cup, the 20.6 cm length covers it without feeling long. If a tall tumbler or a travel mug is your default, the 23.8 cm length is the safer choice, and it still works fine in a normal glass, just with a little more length above the rim. There's no wrong answer here, only a mismatch between the straw and what you actually drink out of most days.
Does the straw length affect how the bracelet fits my wrist?
No, the two measurements are independent. Straw length (20.6 cm or 23.8 cm) is about reaching the bottom of your cup; wrist fit is handled separately by the silicone band, which flexes to fit a normal adult wrist range rather than coming in a chart of sizes you have to measure against first. Choosing the longer straw doesn't mean choosing a bigger or bulkier band: both lengths are built into the same band design, so picking one over the other is purely a question of which cups you drink from most.
Do accessories need to match my wristraw's size?
Yes, for the Extra Straw and the Silicone Case. Each comes in two lengths: 20.6 cm for Slim wristraws and 23.8 cm for Regular ones. A 23.8 cm straw won't fit inside a Slim wristraw, and a 20.6 cm straw is too short to close properly in a Regular one. The Titanium Clasp and Cleaning Brush work with both. Your included accessory follows the same rule, so pick the length that matches your wristraw.
How to measure
Wrap a soft tape measure, or a strip of paper you mark and then measure, around your wrist just past the wrist bone, where a bracelet sits. Read the number. Up to 16 cm (6.3 in) is Slim. 16 cm (6.3 in) and up is Regular. Right at 16? wristraw is made to sit with a little room, so go with Regular.
