You've probably ordered gloves based on price and hoped for the best. Most businesses do. But glove thickness — measured in mil — is the single biggest factor in how a glove actually performs on the job. Get it wrong and you either pay too much for what the task needs, or your team tears through boxes because the glove isn't thick enough to last.
What is a mil — and why do people get it wrong?
A mil is one thousandth of an inch — written as 0.001". It has nothing to do with millimetres. This is one of the most common points of confusion when buying gloves.
A 4 mil glove is 0.004 inches thick. An 8 mil glove is 0.008 inches thick. That difference sounds tiny, but in practice even a 1 mil increase transforms how a glove resists tears and chemicals during critical tasks.
When a supplier describes a glove as "standard", they usually mean 3–4 mil. "Heavy duty" typically means 6 mil and above. Neither term is standardised — which is why knowing the actual mil is more useful than relying on marketing descriptions.
Why the fingertips feel different from the rest of the glove
Here's something most people don't know: the thickness of a nitrile glove is not consistent throughout. During manufacturing, the glove mold is inverted during drying, so the fingertips sit at the lowest point and accumulate a thicker layer of rubber due to gravity — making them the most robust part of the glove. The wrist area is typically the thinnest.
This means when a supplier states a thickness — say, 5 mil — that measurement is usually taken at the palm. The fingertips will be slightly thicker, the cuff slightly thinner. The weakest point of the glove is actually the cuff, not the fingertips.
The practical guide by task
3–4 mil — light tasks, maximum feel
Food handling, sandwich prep, medical examinations, beauty treatments, light inspections. At this thickness the glove offers good tactile sensitivity and dexterity but limited protection against sharp edges or prolonged chemical contact. Not suitable for workshop or industrial use.
5–6 mil — the versatile middle ground
The right range for most business uses: automotive servicing, general workshop tasks, tattoo studios, cleaning with moderate chemicals, food processing. Gloves in the 5 to 6 mil range are dependable for general duty through to heavier automotive or industrial needs involving tools and machinery. This is the thickness most businesses should start with if unsure.
8 mil+ — heavy duty protection
Extended chemical contact, rough industrial work, sharp components, engine stripping. The step up from 5–6 mil makes a real difference to durability. Based on feedback from professional mechanics, at 5 mil you'll typically need 3–4 pairs to get through a full working day of mixed mechanical work — at 8 mil, a single pair can last half a day or more. The trade-off is slightly reduced feel, which matters less when the task is physically demanding.
Thicker is not always better
This is the most important practical point: matching thickness to the task saves money and works better.
A food handler using 8 mil gloves is spending three times more per box than needed, and struggling with less dexterity for no benefit. A mechanic using 3 mil gloves will tear through them in minutes. The goal is fit for purpose — not the thickest glove available.
A surgeon uses 2–3 mil because feel matters more than durability. A mechanic handling brake fluid uses 6 mil or more because chemical resistance matters more than sensitivity. Neither is more "correct" — it depends entirely on the task.
Thickness and chemical resistance
Thicker gloves offer longer breakthrough times — meaning it takes longer for a chemical to penetrate the glove material. For short contact with oils or cleaning agents, 4–5 mil is usually adequate. For extended contact with brake fluid, strong degreasers or industrial chemicals, 6 mil or more is the safer choice.
One important caveat: no disposable nitrile glove resists everything. Brake cleaner, acetone and other ketone-based solvents can penetrate nitrile relatively quickly regardless of thickness. Thickness buys time — not indefinite protection.

FAQ
What does mil mean on a box of gloves?
One thousandth of an inch — not millimetres. A 5 mil glove is 0.005 inches thick. Confusing mil with millimetres is extremely common but the measurements are completely different.
Why does a glove feel thicker at the fingertips?
During manufacturing, glove molds are dipped in liquid rubber then inverted to dry. Gravity causes slightly more material to accumulate at the fingertips, making them the thickest and most durable part of the glove.
What thickness for food handling?
3–4 mil is standard for most food tasks. The priority is dexterity and feel, not durability. For raw meat or oily food, use nitrile rather than vinyl regardless of thickness.
What thickness for automotive or workshop use?
5–6 mil for everyday garage work. 8 mil or above for rough work, engine stripping or extended chemical contact.
Does thicker mean better chemical resistance?
Yes — thicker gloves take longer for chemicals to break through. But no disposable nitrile glove is an indefinite barrier. Always change gloves if they feel sticky, swollen or degraded.
What thickness do tattoo artists use?
Typically 4.5–5.5 mil. Enough puncture resistance for proximity to needles, without losing the precision needed for detailed work.
My team keeps tearing through gloves — what should I switch to?
If you're on 3–4 mil and experiencing regular tears during mechanical or chemical tasks, move to 5–6 mil. If you're already on 5–6 mil and still tearing, try 8 mil for the tasks causing the most problems.
