How Thick Are Smoothie Straws?
Smoothie straws are usually thicker than regular straws and have a diameter of around 0.35 to 0.39 inches, which is approximately 9 to 10 millimeters. The thickness of these straws allows them to handle thicker drinks such as smoothies and milkshakes, making them more enjoyable to drink. However, the length and thickness of smoothie straws vary depending on the brand and type of material used.
