Eyelet tape for curtains: types, sizes and how to use it

Making curtains with eyelets at home or in a workshop can deliver very professional results — provided you use the right materials. One of the most useful materials for that is eyelet tape (or grommet tape): a textile band that, used together with metal eyelets, simplifies installation, reinforces the upper edge of the curtain and ensures perfectly aligned, uniform openings.

What is eyelet tape for curtains?

Eyelet tape — also called eyelet band — is a fabric strip designed to be sewn or applied with iron-on adhesive to the top edge of a curtain. Most types come with pre-marked positions or pre-cut holes for fitting the eyelets, making the work much easier and more precise.

Its main functions are:

  • Reinforce the fabric: The tape adds thickness and strength to the curtain edge, preventing fabric tears.
  • Ease installation: The marked or pre-drilled positions ensure correct eyelet spacing.
  • Provide a clean finish: The tape hides imperfections and keeps the curtain’s top edge straight.
  • Compatibility with hardware: Pre-set hole sizes match standard eyelet diameters.

Types of eyelet tape

Iron-on eyelet tape

The most popular for DIY because it does not require sewing. Just position, iron, and the tape fuses to the fabric. Ideal for medium and lightweight curtains.

Sewn eyelet tape

Recommended for heavy-duty curtains, theatres, hotels and industrial applications. Provides maximum durability and resists frequent washing better than iron-on tape.

Reinforced eyelet tape

Includes additional polymer or fibreglass layers for extreme applications: blackout curtains, very heavy fabrics or oversized eyelets.

Standard sizes

Tape width Inner eyelet hole Typical use
50 mm 25 mm Sheers and lightweight curtains
70 mm 35 mm Standard living room curtains
80 mm 40 mm Heavy curtains, blackout
100 mm 50 mm Theatre/hotel curtains, decorative

How to use eyelet tape

Step 1 — Measure and cut

Cut a piece of tape the same width as the finished curtain plus 2 cm on each side for the side hem.

Step 2 — Fix the tape

For iron-on tape: place the tape on the inside of the top edge with adhesive facing down, and iron with a damp cloth at medium-high temperature for 30 seconds per zone. For sewn tape: sew along both edges with reinforced stitching.

Step 3 — Mark the holes

Most tapes come with pre-marked centres. If not, mark the centre of each eyelet evenly along the tape.

Step 4 — Punch the fabric

Use a hole punch matched to the eyelet’s inner diameter. Punch through both the tape and the curtain at the same time.

Step 5 — Fit the eyelets

Place each eyelet with its washer and press firmly with a manual or bench tool.

Common mistakes to avoid

  • Tape too narrow: Always pick a tape wider than the eyelet diameter for full reinforcement.
  • Poor adhesion (iron-on): Insufficient temperature or time gives weak bonding.
  • Misaligned holes: Take time to mark each centre carefully.
  • Cheap tape: Low-cost tapes may not survive the first wash.
