What is a good UPF rating?

When selecting sun-protective clothing, the UPF rating is a critical factor to consider. This rating indicates the level of UV radiation that a fabric allows to reach your skin. For a robust defense against UV exposure, consider the following UPF ratings:

  • UPF 15 - 24: Good - blocks 93.3% to 95.9% of UV rays are blocked.
  • UPF 25 - 39: Very Good - blocks 96.0% to 97.4% of UV rays are filtered out.
  • UPF 40 - 50: Excellent - blocks 97.5% to 98% or more of UV rays 
  • UPF 50+: Highest - blocks 98% to 99.5% or more of UV rays 

The rated UPF is rounded down to the nearest UPF rating of 15, 30, 50, or 50+

Experts, such as those from the Skin Cancer Foundation, advise choosing garments with a UPF of 30 or above for substantial sun protection. Garments rated UPF 50+ are deemed highly effective, blocking about 98% of UV radiation, which is ideal for prolonged outdoor exposure.


Difference between UPF 30 vs UPF 40 vs UPF 50 vs UPF 50+

Here is a table below with a breakdown of sun protection clothing categories based on their Ultraviolet Protection Factor (UPF) rating:

  • UPF 30 to 40 is considered very good UV protection
  • UPF 40 to 50 is considered excellent UV protection
  • UPF 50+ is considered the highest UV protection

The rated UPF is rounded down to the nearest UPF rating of 15, 30, 50, or 50+



How are UPF ratings Calculated?

Calculating UPF is a scientific process that can't be done easily at home. Here's the gist of it:

Fabric Transmittance: They measure how much UV radiation at different wavelengths (from 280 to 400 nm) passes through the fabric. This considers the biological effects of different UV wavelengths on sunburn (erythema).

Solar Spectrum: They take into account the strength of the sun's UV radiation at various wavelengths.

Calculation: A weighted formula is used to combine the fabric transmittance data with the solar spectrum data. This gives a final UPF value.

The rated UPF is rounded down to the nearest UPF rating of 15, 30, 50, or 50+

Who Performs UPF Testing?   

UPF testing requires specialized equipment and expertise. It's typically done by independent laboratories accredited to follow specific testing standards like those set by the American Association of Textile Chemists and Colorists (AATCC) or the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA).

Are UPF calculations mentioned on the clothing labels?

You won't find the UPF calculation on clothing labels. The label will display a final UPF rating (e.g., UPF 50+) following specific guidelines.
