Straws are available in a variety of diameters based on their intended purpose and function. Sip straws are approximately 1/8" in diameter and used for cocktails and sipping on hot drinks. Jumbo straws are often the standard size for various beverages and measure around 1/4”. Super jumbo straws are also around 1/4” in diameter and some even feature built-in spoons for thick drinks. Milkshakes and smoothies are great for drinking out of giant straws thanks to their 5/16" diameters, and colossal straws at approximately 1/2" in diameter are perfect for frozen concoctions.
