A simple step-by-step guide to choosing the correct Base Cover size for your 24Bottles® bottle. Learn how to measure, match, and avoid common sizing mistakes.
Quick answer
Match your bottle's bottom diameter to the Base Cover size: Small (up to 70 mm), Medium (70-75 mm), or Large (75-80 mm).
Why the Right Size Matters
A Base Cover that's too small won't fit, and one that's too large won't provide a secure grip or protection. The silicone base is designed to snugly wrap the bottom of your bottle, so measuring correctly is key to getting its full benefits: scratch prevention, stability, and a non-slip surface.
How to Choose the Right Base Cover in 3 Steps
- Measure Your Bottle's Bottom Diameter: Use a ruler or measuring tape to measure the flat bottom of your bottle from one edge to the other. If your bottle has a slightly curved base, measure the widest point. A common mistake is measuring the cap instead of the base. Always measure the bottom of the bottle.
- Match Your Measurement to Size: Compare your measurement to the size chart: Small (up to 70 mm), Medium (70-75 mm), or Large (75-80 mm). If your bottle is exactly 70 mm or 75 mm, choose the next size up for a snug but not tight fit. A Base Cover that is too tight can be difficult to remove for cleaning. Slightly larger is better than too small.
- Select Your Color and Order: Once you know the size, pick your color from options like Light Pink, Truffle, or Pine. Add the Base Cover to your cart and install it by stretching the silicone over the bottom of your bottle. Check that the cover sits flush against the base after installation. If it slides off, it may be the wrong size.
