Leather Label Sizes and How to Sew Them On

A leather label looks simple: a small piece of leather with a logo. Yet two practical questions decide whether it looks right on the finished product. How big should it be for this garment, and how will the sewing department attach it so that it lies flat, survives washing and does not tear at the stitch line? This guide answers both, with typical leather label sizes in millimetres and hands-on sewing advice. For materials and logo techniques on denim patches, see our guide to leather patches for jeans.

Leather label sizes by product

Size follows the area where the label sits, not the logo. Measure the flat space available, subtract room for stitching and seams, then fit the logo inside. The table gives typical starting points; custom sizes and die-cut shapes are always possible.

How to choose within a range

• Leave a margin. If the label sits on a waistband or cuff, keep 2–3 mm free at the top and bottom so the stitching does not run into seams or the fold.
• Respect the logo. Embossed or debossed logos need space around them. As a rule, keep the logo at least 4–5 mm inside the stitch line so needle holes never cut through a letter.
• Think in proportion. A label that is too large looks heavy on a lightweight item; on a beanie, a 50×25 mm label usually looks balanced, while a chunky winter knit can take 60×30 mm.
• Match thickness to the base fabric. Thin, supple leather on knitwear and beanies; thicker, firmer leather on denim, bags and canvas.

Why thickness matters for sewing

Leather labels are typically between 0.8 and 2.0 mm thick. Thicker labels feel more substantial and hold a deeper embossing, but they need a stronger needle and a machine that can climb over the edge without skipping stitches. Thin labels sew easily and follow the curve of a knitted cuff, but very thin leather can stretch at the stitch line. If you are unsure, ask for samples in two thicknesses and sew both on your machine.

How to sew leather labels: stitching patterns

Perimeter stitching

A single line of stitching runs around all four sides, usually 2–3 mm in from the edge. It holds the label completely flat, stops the edges curling after washing and gives a clean, finished frame. Perimeter stitching is the standard for jeans patches, bags and jackets.

Two-side stitching

Only the two short sides are stitched, often as a short bar or a double line. This is quicker and leaves the long edges free. It suits labels on hems and side seams, and labels inserted into a seam with only one end visible.

Corner stitching

A small cross, bar or a few stitches are placed only at each corner, often through pre-punched holes. The label is held securely, but the fabric between the corners can still stretch. This is the preferred method for beanies, knitwear and other elastic fabrics, where a full frame of stitching would stop the knit moving and cause puckering.

Sewn into a seam

A flag or tab label can be inserted into a seam, for example on a side seam or bag gusset, and fixed with the seam itself. Only one end is caught, so the label must be long enough to sit in the seam allowance securely.

Needles, thread and stitch length

• Needle for genuine leather: a leather needle with a cutting point (wedge point) slices cleanly through the hide. Sizes around NM 90–110 suit most labels; use the heavier end for thick labels on denim.
• Needle for PU and jacron: a sharp or regular point is usually better, because a cutting point can weaken coated or paper-based materials along the stitch line.
• Thread: bonded polyester or nylon thread is strong and resists abrasion. Choose a heavier thread for denim and bags, a finer one for knitwear. Tone-on-tone thread lets the logo speak; contrast thread makes the frame part of the design.
• Stitch length: use a longer stitch, about 3–4 mm. Very short stitches perforate the leather like a tear-off line and can make the edge break.
• Presser foot: a walking foot or roller foot feeds leather evenly; a non-stick foot helps on PU surfaces that tend to grip.

Pre-punched holes for hand sewing

For small runs, knitwear and products finished by hand, leather labels can be supplied with pre-punched stitch holes at the corners or along the edges. The holes keep spacing even, make hand sewing fast with a blunt needle and waxed or strong thread, and help small studios achieve a professional result without a heavy machine. Tell us the hole layout you need, for example two holes at each short end or one hole in each corner.

Beanies and knitwear: practical notes

On beanies, the label is usually placed on the turned-up cuff, centred at the front. Decide whether you sew through one layer of the cuff or both: through one layer the inside stays clean and comfortable, through both the cuff is fixed in place. Use corner stitching or short side bars so the rib can still stretch over the head. Sew with the beanie slightly stretched to the size it will be worn at, otherwise the label may pucker when it is on. A soft, thinner leather or PU around 0.8–1.2 mm follows the curve better than a stiff 2 mm label.

Rivets and other fixings

Where sewing is awkward, for example on finished bags, thick canvas or some hats, leather labels can be fixed with rivets. One rivet at each end, or one in each corner, gives a rugged, workwear look, and the rivet head becomes part of the design. Our metal components are nickel-free and can be finished to match your other hardware; see the metal labels guide for finishes. Leather labels can also be supplied with a heat-activated adhesive backing for positioning, but for garments that are washed, stitching or rivets should always provide the permanent hold. For the general pros and cons of adhesive attachment, read sew-in vs iron-on labels.

Washing after attachment

If the garment is washed after the label is sewn on, as most denim is, the label goes through the same process. Leave a little ease in the stitching so a genuine leather label can move slightly if it shrinks, and test a sample through your real wash recipe before bulk production. PU and jacron labels are often chosen precisely for washed garments.

Ordering leather labels

Send us your logo, the product, the size and thickness you have in mind and how you plan to attach the label: perimeter stitching, corner stitching, pre-punched holes or rivets. Our designers prepare a dimensioned drawing with stitch margins and a digital proof, typically within 24–48 h, and physical samples are available before production. The minimum order is usually 1,000 pcs per design, and production typically takes 10–20 working days after approval, in our own production in Bulgaria.
