BFY / SIZING & FIT

Find your fit.

Product sizing information stays here with Befitting You. Our team can help confirm measurements and fitting requirements.

BioSkin lists XS-M and L-XXL for this thumb-length-sized model, with the same design for left and right hands. Contact BFY for fit assistance, including shared size boundaries or measurement details.

BioSkin Thumb Splint / Thumb Spica sizing

Measurement: Length of thumb.

BioSkin Thumb Splint / Thumb Spica sizing — sizing reference
SizeThumb length (inches)Thumb length (centimetres)
XS - M3.25 – 4.258 – 11
L - XXL4.25 – 5.2511 – 14
  • This chart is specifically linked from BioSkin's exact Thumb Splint / Thumb Spica model page.
  • Sizing uses thumb length, not wrist circumference. The chart labels the measurement Length of thumb and supplies a hand illustration, but no more detailed written measurement endpoints.
  • Inch and centimetre ranges are transcribed independently as published; they are not recalculated conversions.
  • The shared boundaries of 4.25 inches and 11 centimetres are preserved without an invented endpoint-selection rule.
  • BioSkin lists XS-M and L-XXL and explicitly states the model is universal for left and right; this does not mean it is one-size.

Sizing is a product reference, not a treatment recommendation or a guarantee of fit. If you are between ranges or unsure of a measurement, talk with BFY before choosing a size.
