Piping tip numbers explained

Piping tips are numbered, and the numbering is not arbitrary — it follows a system originally set by the large American manufacturers that most makers now copy. Once you can read it, a drawer of loose tips becomes usable.

The families

Tips group by the shape of the opening, and the number tells you which family and roughly what size.

• Round (numbers 1–12 and up) — a plain circle. Writing, dots, beads, outlines, filling. The number is roughly the aperture: a 2 is fine writing, a 12 is a fat bead.
• Star (13–22, and the open star series) — the workhorse. Rosettes, shells, borders, swirls on cupcakes. A 1M and a 2D are the two large stars almost every cupcake photograph uses.
• Leaf (65–70) — a V-shaped slot producing a pointed leaf with a central rib.
• Petal (101–127) — a teardrop slot, wide at one end. Roses, ruffles, ribbon. The higher numbers are considerably larger.
• Basketweave (44–48) — flat on one side, serrated on the other, for woven basket textures.
• Specialty — grass and hair (233), drop flowers (2D, 1G), ruffles.

Within a family, a bigger number means a bigger tip. Across families the numbers are not comparable.

The five tips that do most of the work

If you never bought another, these five cover almost everything a home decorator does.

1. Round 3 or 4 — writing, outlines, dots.
2. Open star 21 or 22 — shell borders, small rosettes, textured coverage.
3. Large star 1M — the cupcake swirl. One tip, one technique, and it makes anything look finished.
4. Leaf 67 — leaves, and the only reasonable way to make them.
5. Petal 104 — roses and ruffles.

A 158-piece kit contains these five and 153 other things. That is not a criticism of the kits — it is why a kit is good value for a beginner, because you do not yet know which five you use.

Why a numbered set matters

Tips that carry their number stamped on the side are findable. Unnumbered tips are a drawer of similar metal cones, and matching one to a tutorial means holding it up against a chart.

When a kit includes a pattern chart showing what each numbered tip produces, that chart is a real part of the value. Keep it.

Where a manufacturer states that tips are numbered, our listings say so.

Couplers

A coupler is a two-part plastic fitting: the inner part goes in the bag, the tip goes over it, and the ring screws on to hold it. It lets you change tips without emptying the bag.

Without one, changing from a star to a round means a new bag or emptying the old one. Any kit that includes couplers is saving you real time.

The limit: standard couplers only fit standard-size tips. Large tips — 1M, 2D and the rest of the big series — go straight into the bag with no coupler, because no coupler is large enough.

Standard and large

Two size classes, and they are not interchangeable.

Standard tips fit a coupler and suit small work on cakes and cookies.

Large tips are wider at the base, drop straight into the bag, and are what you want for cupcake swirls and thick borders. Trying to do a full cupcake swirl with a standard star is slow and the result is thin.

Check which class a set is before buying, particularly if you already own couplers.

Stainless steel and plastic

Stainless steel tips hold a crisp edge, survive dishwashers and last indefinitely. Plastic tips are cheaper, lighter, and the fine edges soften over time so the pattern loses definition.

For anything you will use repeatedly, stainless is the better purchase. Where a maker states the material we repeat it.

Cleaning

Rinse tips immediately — buttercream sets hard inside the cone and is a genuine nuisance later. Soak in hot soapy water and use a narrow brush to get inside the slot; a leaf or petal tip cannot be cleaned by rinsing alone.

Dry thoroughly. Even stainless tips will spot if left wet, and the seam is where it starts.

Store tips in a compartment box rather than loose. A dented tip pipes a distorted shape and cannot be corrected.

What to buy first

For a first purchase, a numbered kit is better value than five individual tips, and it comes with bags, couplers and the chart. Once you know which tips you reach for, buy those individually in stainless steel and keep the kit for the rest.

On the shelf

Tips, bags and coupler sets are on the piping bags and tips page. The full beginner sets — tips, bags, turntable, spatulas and chart together — are under complete decorating kits. Turntables on their own are at turntables and stands, and scrapers, levellers and spatulas are under icing tools and spatulas.
