Size & Cup-Holder Fit Guide

Find the HydroJug that fits your routine – and your cup holder.

HydroJug bottles come in a range of sizes so you can choose what’s most comfortable for your hand, backpack, stroller, or car. Use this guide to compare dimensions, capacities, and base diameters. When checking cup-holder fit, measure the inner diameter of your holder and leave a little clearance for easy in-and-out.

How to Check Cup-Holder Fit

1. Measure the inner diameter of your car’s cup holder at the tightest point (rubber tabs or grips reduce usable width).
2. Compare to the base diameter listed below.
3. Leave clearance of about 0.1–0.2 in so the bottle slides in/out smoothly.
4. Remember add-ons: sleeves and silicone boots add bulk and may affect fit.

Quick Key (guidance varies by vehicle)

• ≤ 2.80 in (≤ 71 mm) – fits most standard holders
• 2.81 – 3.05 in (72–77 mm) – fits many; check tabs or grips
• 3.06 – 3.25 in (78–83 mm) – larger and adjustable holders only
• > 3.25 in (> 83 mm) – rarely fits; confirm before purchase

Tips for a Perfect Daily Carry

• Driving a lot? Favor bases ≤ 3.0″ for easy in/out.
• Using sleeves or boots? They add bulk; test fit without them.
• Strollers and gym machines: measure the slot just like a car holder.
• Backpacks and side pockets: check pocket depth against bottle height so it stays secure.
  

FAQs

How do I know if a bottle will fit my car’s cup holder?
Measure the inner diameter at the narrowest point. Compare with the bottle’s base diameter and leave clearance.

Do sleeves or silicone boots affect fit?
Yes. They add bulk and can reduce compatibility.

My cup holder has rubber tabs – what do I check?
Measure between the tabs (the narrowest span).

Which HydroJug models are most cup-holder friendly?
Traveler 20/32/40, Sport 14/20/32, and Insulated Shaker 24 are the most likely to fit standard holders.

Will the Sport 40oz or Traveler 40oz fit?
They can fit many large or adjustable holders. Always compare your holder diameter to the base: Sport 40 (~3.14"), Traveler 40 (~3.04").

Do the large jugs fit?
Sport 64oz and Pro V2 73oz are not designed for vehicle cup holders.
