COMPRESSION GUIDE
15–20 vs. 20–30 mmHg Knee High
The main difference is pressure intensity, measured in millimeters of mercury (mmHg).
20–30 mmHg provides firmer compression than 15–20 mmHg and can deliver roughly 25% to 50% more pressure,
depending on where within each stated pressure range the garment is operating.
15–20 mmHg
Moderate Compression
Pressure and Fit
Offers moderate compression that gently supports circulation and can help reduce minor leg fatigue without feeling as tight or restrictive as firmer compression.
Ease of Use and Comfort
Generally easier to put on and take off, making it a comfortable choice for all-day wear and a more approachable starting point for people new to compression.
Common Uses
Commonly chosen for general leg fatigue, long flights, mild travel swelling, early spider veins, and prolonged sitting or standing.
Ozer Product Construction
The current Ozer 15–20 mmHg knee-high insert card lists an 80% nylon / 20% spandex construction. Use its dedicated sizing card when ordering this product.
20–30 mmHg
Firm Compression
Pressure and Fit
Offers firm compression and applies noticeably stronger pressure than 15–20 mmHg. This firmer level is often used when more substantial graduated support has been recommended or is desired.
Ease of Use and Comfort
Requires more physical effort to put on because of the tighter fit and can feel more restrictive if a firmer level is not needed.
Common Uses
Commonly used for moderate swelling, prominent varicose veins, recovery after certain procedures, situations involving DVT risk, and more intensive recovery support. For medical conditions, post-procedure use, or clot-related concerns, use only with guidance from a qualified healthcare professional.
Ozer Product Construction
The current Ozer 20–30 mmHg knee-high insert card lists an 85% polyester / 15% spandex construction. Use the separate 20–30 mmHg sizing card for this product.
The key difference
15–20 mmHg = lighter, moderate pressure. 20–30 mmHg = firmer pressure. The 20–30 mmHg range can deliver about 25% to 50% more pressure than the 15–20 mmHg range, depending on the comparison point within each range.
Because the two Ozer knee-high products use different constructions and product-specific measurements, their sizing information should not be treated as interchangeable.
Important medical note: Compression products are not appropriate for everyone. If you have a diagnosed vascular condition, are recovering from a procedure, have concerns about blood clots, or have been told to use compression by a clinician, follow the advice of a qualified healthcare professional regarding compression level, fit, and duration of wear.
