Glove sizing fails when clinics buy by headcount instead of by hand measurement, and the cost shows up as tears at the fingertips, double-gloving and staff who quietly take a larger box from another room. Fit matters more than thickness because a stretched nitrile film loses barrier performance before it visibly fails. Measure hands once, map staff to sizes, and stock the ratio your staff actually needs.
Two measurements are enough: hand circumference around the palm and hand length from wrist to fingertip. A 4.0 mil powder-free nitrile examination glove in the right size gives better protection than a thicker glove that is too small.
How do you measure a hand for glove sizing?
Wrap a tape measure around the widest part of the palm, just below the knuckles, and record the circumference. Measure the length from the base of the wrist to the tip of the middle finger. Compare both to the manufacturer's size chart, because a hand can sit between sizes on one measurement and inside a size on the other.
| Size | Palm circumference (guide) | Hand length (guide) |
|---|---|---|
| XS | Under 16 cm | Under 16 cm |
| S | 16 to 18 cm | 16 to 17 cm |
| M | 18 to 20 cm | 17 to 18 cm |
| L | 20 to 22 cm | 18 to 19 cm |
| XL | Over 22 cm | Over 19 cm |
These are guides, not a standard. Size charts differ between manufacturers, so use the chart for the product you actually stock. A clinic that switches brands without re-fitting will see a spike in tears.
What does a correct fit feel like?
Make a fist and spread the fingers. The glove should not pull across the web between thumb and index finger, the fingertips should not feel tight, and the cuff should sit at the wrist without sliding down the forearm. If the web pulls, go up a size; if the cuff is loose and the fingertips are baggy, go down. A glove that feels comfortable at rest but tight when gripping is a size too small for clinical work.
Check the fit with the tasks staff actually do: opening a sterile pack, drawing up a syringe, holding an instrument. A glove that passes the fist test can still fail during a pinch grip if the fingertips are too short.
Why do clinics get the stock ratio wrong?
Because they order by what they think staff should wear, not by what staff do wear. A clinic that stocks 60% medium often finds that half the team is wearing large and medium is left on the shelf. The result is a shortage of one size and a surplus of another, with staff compensating by double-gloving or using a size that does not fit.
Run a one-time fitting at the door and record the size each staff member takes. Then build the order ratio from that list, not from a national average. Review it once a year and whenever a new team member joins. The Moncton clinic case in our library describes the same approach applied to consumption rather than stock, and the two work together.
When does thickness matter?
Thickness matters for mechanical load and wet grip, not for fit. A 4.5 mil fully textured glove, such as the Robust nitrile examination glove, suits longer procedures and wet work where a thinner glove would abrade. It does not fix a sizing problem, and it does not improve chemical permeation resistance unless the glove is rated for the chemical.
Offer two thicknesses at most. A clinic that stocks four products tends to have gaps in the sizes that matter and surplus in the ones that do not.
How should fitting be documented?
Keep a simple list: staff name, size, product, date fitted. Review it at onboarding and annually. It takes a few minutes and prevents the recurring cycle of complaints, exchanges and double-gloving that costs more than the gloves. If a staff member reports tears at the fingertips, check the list first: a recent change of product or size is the usual cause.

Frequently Asked Questions
How do I know my glove size?
Measure the palm circumference below the knuckles and the hand length from wrist to middle fingertip, then compare both to the manufacturer's chart for the product you stock.
What if I am between sizes?
Choose the size that does not pull across the web when you make a fist. For clinical work, a slightly larger glove is usually better than one that restricts grip.
Does a thicker glove last longer?
It resists abrasion longer, which suits wet and longer procedures. It does not improve fit and does not add chemical protection unless the glove is rated for that chemical.
How many glove sizes should a clinic stock?
Stock the sizes your staff actually wear, based on a fitting list, with two thicknesses at most. Order ratios from the list, not from a national average.
