17+ Different Types of Zippers for Sewing for Women With Pictures

Construction is everything. Before a zipper has a color or a length or a brand name stamped on the pull — it has a tooth identity. Are the teeth molded plastic, coiled nylon, or cast metal? Each choice carries weight implications, flexibility implications, and yes, aesthetic implications that shape the entire garment around it. These six types represent the fundamental what of the zipper: how the chain is built, how the slider engages, and what structural logic locks the closure into place.

What works beautifully about this classification is that it cuts through the noise of brand language. A "heavy-duty nylon zipper" is marketing. A continuous-coil nylon chain with a size-5 slider and a locking mechanism? That's construction. And construction tells you how a zipper will perform, flex, and age — which is the information that actually matters when you're choosing closures at the fabric store or ordering online.

Closure style is a modifier — and a crucial one. A separating zipper and a closed-end zipper use identical chain construction but behave in completely different ways at the bottom stop. This is why you can't substitute one for the other without redesigning the garment's opening system. How a zipper closes, where it stops, and whether it fully separates determines everything about how the garment is put on, taken off, and worn. Get this wrong and the garment simply doesn't function.

Application context is where zipper selection becomes genuinely interesting — and where most beginner mistakes happen. The zip that works perfectly in a dress will fail catastrophically in a boot. The one engineered for a sleeping bag has no business in a structured bodice. Garment-specific zipper types differ in tooth size, tape width, slider profile, stop construction, and chain material weight. These are functional engineering decisions, not aesthetic ones. Understanding them transforms your sewing from guesswork into precision.

Specialty zippers? They're where the category gets genuinely fascinating. A continuous zipper chain sold by the meter with separately purchased sliders. A magnetic closure that mimics zipper function for people who can't manage fine motor tasks. Molded decorative zippers with resin pulls shaped like flowers, skulls, or lightning bolts — the tooth and tape are functional, but the pull is art. These aren't niche in the dismissive sense. They solve real problems that standard zipper types cannot.

This is also the category that rewards the most research. The most recently published industry surveys on fastener innovation (through 2024) indicate specialty closures — magnetic, continuous-chain, and hybrid systems — represent the fastest-growing segment of the global zipper market, driven partly by adaptive clothing demand and partly by fashion designers seeking closure solutions with fewer visual constraints.

Zipper chain size — that number stamped on the slider (size 3, 5, 7, 8, 10) — refers to the approximate width of the closed chain in millimeters. It's not a quality rating. It's a structural specification. A size 5 chain is 5mm wide when closed. That measurement determines how much seam allowance the zipper needs, how much pull force the slider exerts, and whether the tooth profile is appropriate for the fabric weight it's being sewn into. The table below is the practical translation of those specifications into everyday sewing decisions.

What is the most common type of zipper used in sewing?

The coil zipper — also called a nylon zipper — is the most widely used type in home sewing and garment production. Its continuous spiral nylon chain makes it lightweight, flexible, and suitable for curves. It installs reliably in dresses, skirts, bags, and most casual wear. According to the most recently available industry data from 2024, nylon coil zippers account for the majority of zipper units sold globally across all applications.

What is the difference between an invisible zipper and a regular zipper?

An invisible zipper — also called a concealed zipper — uses a coil chain that curls away from the garment face, creating a seam that looks continuous when closed. A regular zipper's teeth face outward and are visible as a design element or covered by a fabric placket. Installation differs significantly: invisible zippers require an invisible zipper foot and are pressed open before stitching, while regular zippers are sewn with the chain visible and a zipper foot alongside it.

What does zipper size (size 3, 5, 8) mean?

The size number refers to the approximate width of the closed zipper chain in millimeters. A size 3 chain is roughly 3mm wide when engaged; a size 8 is 8mm. Higher numbers indicate larger teeth, heavier tape, and more pull force — appropriate for heavier fabrics and more demanding applications. Choosing the wrong size for a fabric weight is one of the most common causes of zipper failure in both home sewing and production garments.

Can I use a separating zipper in a skirt or dress?

Generally, no — and this is a common beginner mistake. A separating (open-end) zipper is engineered for garments that need to fully divide at the bottom: jackets, hoodies, cardigans. Skirts and dresses use a closed-end zipper, which has a permanent bottom stop so the seam doesn't fully open. Installing a separating zipper in a skirt seam typically results in an unstable bottom opening that can't be properly topstitched.

What zipper type works best for a jacket or hoodie?

A separating (open-end) zipper — typically a size 5 coil for lighter fleece or a size 5–8 molded tooth for heavier outerwear. The separating mechanism is non-negotiable: without it, the garment cannot be put on like a jacket. For technical outerwear in cold or wet climates, a waterproof sealed zipper with a locking slider is worth the additional cost and installation complexity.

How do I shorten a zipper that's too long?

The standard method: mark the required length, sew several bar tacks across the chain at that point with a sewing machine zig-zag stitch (or hand-whipstitch the chain closed), then cut the excess tape 1 inch below the new stop. Do not cut the zipper before creating the new stop — a slider without a stop will simply pull off the chain. This technique works for coil and molded tooth zippers; metal zippers may require pliers to remove teeth before creating the stop.

What are waterproof zippers made of?

A waterproof zipper uses standard coil or tooth chain construction bonded with a thermoplastic polyurethane (TPU) membrane laminated to the tape and sometimes the teeth. The membrane creates a seal that prevents liquid from passing through the closed zipper. These differ from water-resistant zippers, which are treated with a DWR (durable water repellent) coating that repels surface moisture but does not prevent sustained penetration.

What is a continuous zipper chain used for?

Continuous zipper chain — sold by the meter — is used when standard pre-cut zipper lengths don't match the application, or when multiple zippers of custom lengths are needed efficiently. Common in upholstery, multi-pocket bags, production sewing, and zipper pouches. Sliders are purchased separately and installed by threading the chain through the slider mechanism, with stops added manually via zig-zag bar tack or metal crimp stops.

Here's what most online zipper guides skip completely — and it's arguably the most practical part of the whole subject. Zipper failure in home-sewn garments is almost never about the zipper itself. It's about three mismatches: wrong tooth size for fabric weight, wrong tape width for seam allowance, and wrong slider profile for the garment's opening angle. The zipper is fine. The selection process was wrong.

The "opening angle" problem nobody talks about.

Most zippers pull vertically in a straight seam. But some applications — curved waistbands, angled pockets, shaped side seams — require the slider to travel a non-linear path. Coil zippers can accommodate mild curves. Molded tooth zippers cannot. Metal zippers cannot. Installing a molded tooth zipper in a curved seam creates chain tension that will eventually split the stop or pull the tape off-grain. This is a zipper selection failure, not a sewing error.

The slider pull direction matters.

Standard sliders open toward the pull. But right-hand pull and left-hand pull versions exist — and installing the wrong one means the zipper closes toward the hem instead of opening toward it, or the pull tab faces inward against the body. For invisible zippers specifically, slider orientation determines whether the coil curls toward or away from the seam face. Always confirm slider pull direction before installation, especially on reversible garments or two-way zipper applications. It's not obvious from the packaging.

Pressing is not optional.

Invisible zippers must be pressed open — the coil needs to uncurl from the tape before the presser foot can engage close enough to the chain. Most sewists who struggle with invisible zippers haven't pressed the coil open with a low iron before installation. That single step changes the result completely. It's not in most quick tutorials because it adds thirty seconds and photographs awkwardly. Do it anyway.
