Choosing Your Glass Straw

Choosing the right glass straw size may seem like a daunting task, so we're here to simplify it.


There are only four things to consider:

  • Diameter
  • Length
  • Straight or Bent
  • Decorated or Plain

Straw Diameter


Generally, the thicker the beverage, the bigger you want the inside diameter of your straw to be.


Our 15mm Bubble Tea/Boba Teastraws (10mm inside dimension) are perfect for drinking boba pearls. If you're a Boba Tea drinker, this straw is for you.  Comes in 8" or 10" lengths.

8mm Skinny Straws (4mm inside dimension)

  • Great for hot drinks
  • Fits smoothly into the lid of a Starbucks reusable cup, and "to go" cups from your favourite coffee place
  • The Skinny straws are more delicate than our thicker straws, so only a few of our designs have this option

9.5mm Regulars (5.5mm inside dimension)

  • Our most popular diameter
  • They are good for juice, soft drinks, water, and well-blended smoothies

12mm Smoothies (8mm inside dimension)

  • Perfect for smoothies, milkshakes and other icy drinks
  • We also recommend them for young children - they are more durable, and little hands find them easier to hold onto than the thinner straws

Straw Length

Tip: Measure your drinking vessel, then add 2-3 inches

In choosing the length of your GlassSipper it may be helpful to know that most "disposable" plastic straws are 8-9 inches

6-7 inch Straws

  • for mugs, tea cups, wineglasses, kids cups, cocktails

8 inch Straws

  • for soda pop cans, most standard bottles, most standard barware, mason jar mugs, 16 oz 'to-go' cups,16 oz bottles

9-10 inch Straws

  • for standard soda pop and beer bottles, Starbucks 'vente' 24 oz reusable or 'to-go' cups, large mason jars, 20 oz soda pop bottles, 24 oz bottles

Because we make each straw by hand, we can easily customize a non-standard length for you.  Ask us!

Straight or Bent

This is a personal preference. Many customers who can't decide at first, get one of each.

Customers with disabilities who have difficulty grasping their straw often prefer bent straws.

Both straight and bent straws clean easily in the dishwasher and under the tap.


Decorative or Plain

This too is a personal preference. We believe that even our plain straws have an elegant beauty, but choosing a GlassSipper with a design or critter will make drinking your beverage more fun, visually pleasing, and serve as a great conversation starter.  The decorated straws can be a bit more fragile, so if you're worried about breakage, opt for a plain one for every day and travel and a decorated one to use on special occasions.

Most of our customers fall in love with their straws, and we believe you will too. GlassSippers make wonderful gifts for friends and family - and are great for our planet.
