How to Size Your Nose for Max-Air Nose Cones | Sinus Cones

It’s easy to determine what size of Max-Air Nose Cones or Sinus Cones to order.

“I bought the medium and large Max-Air Nose Cones to get the right fit and send the other size back. The medium fit is just right, so I am returning the large one for a refund. Thank you and the product is working great!”

Your fingers are correlated to the inside size of your nose, and we have developed a patented formula that uses the width of your thumb to gauge the size of your nasal airway and the most suitable size Cone.

(No need to put your thumb in your nose. Just use this simple method and let our sizing system do the rest.)


  1. Place your thumb at the beginning edge of a ruler, press down on the ruler and then find the widest measurement mark showing on the ruler.
  2. Measure the entire width of the thumb (including the skin) from the left side to the right side, as shown.
  3. Use our sizing chart as reference to determine what size Cones to order based on the width of your thumb.

If your thumb measures:

3/4″ (.75 of an inch) or less, select the size small.

If your thumb measures more than 3/4″ to 1″ (.75 of an inch to one inch), select the size medium.

If your thumb measures more than 1″ (more than one inch), select the size large.

If you are right on the line between two sizes, we suggest ordering both sizes, trying them and then returning the ones that are not the correct size. Please see our guarantee for details.

PLEASE NOTE: sometimes your nasal airways are not the same size, and consequently, two sizes are necessary for proper fit. If this is the situation with your nasal airways, try each size in each airway to determine which size fits which nasal airway best.

Custom Sizing for Deviated Septum and Nasal Airway Collapse

Mixing two different sizes may be needed for deviated septum or nasal valve collapse, if one nasal airway or nostril is smaller or narrower than the other.

If this is your situation, you will find it more suitable to use two different sizes Cones to treat this problem. Simply determine the size that you measure to normally, as indicated above, and then select that size for your larger nostril, and the next smaller size for your other smaller or narrower nostril.

Purchase the two sizes, and use one size in one nostril and the other size in the other nostril. Once again, swivel for your most comfortable fit and best angle to maximize flow volume.

How to Choose Your Most Comfortable Softness

Every person is slightly different when it involves the softness that they prefer. Generally the softer, clear, Max-Air Nose Cones are preferred, especially for deviated septum, mild sleep apnea, snoring, and night time dry mouth.

The original, white comfort-soft Sinus Cones may be best for those nights when nasal allergy, sinus or cold congestion is severe and extra nasal airway support is necessary, or when nasal obstruction from a blocked nose or collapsed side-wall is present. Sinus Cones and Max Air Nose Cones
