Vinyl Thickness Guide: 0.8mm vs 1mm vs 1.2mm, Which Do You Need?

Written by the Kehls team · Last updated: 16 September 2026

For everyday household furniture, 0.8mm Regular Vinyl is enough. Outdoor pieces and higher-wear areas want 1.0mm All Purpose Vinyl. Restaurants, clinics, schools, offices and public seating need 1.2mm Contract Vinyl. Decorative, low-wear projects suit 0.7mm Economical Vinyl. Thicker vinyl wears longer; thinner vinyl shapes more easily around curves.

The question we hear most across the counter is some version of “which vinyl thickness do I need?” It deserves a straight answer, so this vinyl thickness guide gives you the verdict first and the reasoning after. Every thickness below maps to a range we stock, sold by the metre, so you buy exactly what the job needs. For colour ranges, care and everything beyond thickness, our full upholstery vinyl guide covers the rest.

The decision table: every Kehls thickness at a glance

Match the vinyl to the traffic it will see, not to the biggest number on the label. Upholstery vinyl does its best work in the 0.7mm to 1.2mm band, and our ranges cover that band end to end; if you were searching for the average vinyl thickness, that band is your answer.

The 0.8mm Regular tier is our broadest, with the Paradise, Paradise Rainbow and Savannah ranges all sitting at that thickness. That is deliberate: it is the thickness most projects actually need.

What thickness actually changes

Thickness is a trade, not a ladder. When you compare vinyl material thickness, four things move together:

• Wear and puncture resistance: more material between the world and the foam means more rubbing, scuffing and poking before trouble shows.
• Seam strength: thicker vinyl holds a stitched seam under more strain. Stitching is essential for seating at any thickness; adhesive belongs on flat decorative installs only.
• Handling: every step up in thickness makes the sheet stiffer around corners, piping and buttoning. Thinner vinyl drapes and shapes more easily.
• Weight: heavier rolls, heavier finished pieces. It matters on doors, panels and anything wall-mounted.

“Most people ask for the thickest vinyl we stock. Most leave with 0.8mm, because that is what their furniture actually needs.” (Trade counter assistant, Kehls)

Key takeaway: thickness buys durability at the surface and the seam, and it spends pliability at the curve. Buy durability where traffic demands it, and pliability where the shape demands that.

Scenario snapshot: six kitchen chairs, a family of four, wipe-downs after supper. That is general household duty: 0.8mm vinyl, stitched seams, done. The same chairs in a busy waiting room would climb to 1.0mm or 1.2mm before we would call it settled.

Gauge and mil to millimetres: converting American charts

American tutorials and imported spec sheets quote vinyl in gauge or mil, so a vinyl fabric gauge thickness chart can feel like another language. The key is the mil: one mil is one thousandth of an inch, which is 0.0254mm (NIST unit tables). Here is the vinyl mil thickness chart translated for our shelves:

So 16 gauge vinyl thickness in mm is roughly 0.40mm, but treat gauge with caution: it is not fully standardised across products, and two suppliers’ “20 gauge” can differ. Mil is at least defined; millimetres are clearest of all, which is why we quote every range in mm.

When thicker is not better

Myth: the thickest vinyl is always the best vinyl.

Reality: once a vinyl can handle the traffic, extra thickness stops adding value and starts fighting you. Thinner vinyl is not lesser; it is the right tool for different jobs:

• Tight radii and piping: a supple 0.7-0.8mm sheet follows small curves without bunching or bridging.
• Deep buttoning and diamond stitch: pleats need material that folds crisply. Heavy contract vinyl resists exactly the movement this work depends on.
• Headboards and wall panels: these see hands, not seats. Low wear plus complex shaping is the textbook case for 0.7-0.8mm, and flat decorative panels can be glued rather than stitched.

“On a deep-buttoned headboard, a supple 0.7mm vinyl gives you crisper pleats than any heavy contract roll. Pliability is the feature, not the compromise.” (Branch upholstery advisor, Kehls)

How to check vinyl thickness before you buy

Wondering how to measure vinyl thickness accurately? Use digital callipers on a clean-cut edge of a sample, take readings at three or four points, and use the average. If the vinyl carries a foam backing or fabric scrim, check whether the quoted figure describes the wear layer or the full build, because the two read very differently under callipers.

Or skip the callipers entirely. Request free fabric samples, pop in-store and feel the difference between 0.8mm and 1.2mm vinyl in your hands, or WhatsApp your nearest Kehls branch with a photo of the piece. Describing the setting is usually enough for us to confirm the thickness on the spot.

The easy next step: free fabric samples

Since 1970 we have supplied affordable and quality vinyl to the Upholsterer, Motor Trimmer and Public, and the right thickness is where every good job starts. Whether you’re recovering one kitchen chair or fitting out a clinic, decide with the vinyl in your hands rather than off a screen.

Order your free fabric samples through our contact page, or pop in-store in Cape Town (Maitland), Pinetown or George. Vinyl is sold by the metre, and we offer free delivery in and around Cape Town, Monday to Friday. Once you know which vinyl thickness you need, the rest of the project gets simpler.

FAQ

Does vinyl thickness matter?

Yes, it is the main durability lever you control at purchase. Thicker vinyl resists wear and punctures for longer and holds stronger seams, which is why heavy-traffic public seating calls for 1.2mm Contract Vinyl. But thickness should be matched, not maximised: past the needed level it only adds stiffness and weight. Care matters just as much, since quality vinyl properly looked after maintains flexibility and resists cracking for years.

How thick is 20 gauge vinyl?

For vinyl film, 20 gauge is approximately 0.50mm, and 16 gauge is roughly 0.40mm. Treat these as approximations, because gauge is not fully standardised across products and suppliers. Both sit below 0.7mm, the lightest thickness we stock for upholstery work. When comparing products, ask for the millimetre figure; it is the one measurement everyone defines the same way.

What thickness do I need for restaurant seating?

It depends on the traffic. For moderate-traffic seating, 0.8mm Regular Vinyl is suitable and is widely used in waiting rooms, salons and quieter restaurants. For busy venues with constant daily turnover, step up to 1.2mm Contract Vinyl, which is built for restaurants, hotels and public seating. If you are between the two, describe the venue to your nearest Kehls branch and we will confirm.

What thickness should I use for boat seats?

Outdoor and higher-wear settings point to 1.0mm All Purpose Vinyl, which balances strength with enough flexibility to shape around cushions and contours. Marine conditions add sun, salt and moisture on top of ordinary wear, so before cutting, check with your branch which specific ranges suit those conditions. Request free samples and test them where the boat actually lives.

What thickness is right for kitchen chairs and headboards?

Kitchen chairs are general household furniture, so 0.8mm Regular Vinyl is the standard answer: durable enough for daily use, supple enough for corners and piping. Headboards flip the logic. They are low-wear and often deeply buttoned, so 0.7mm Economical Vinyl shapes more crisply, with 0.8mm as the step up if the piece will take regular knocks.
