What Size Are Tila Beads? Dimensions and How Many You Need for a Bracelet
What Size Are Tila Beads?
A standard Miyuki Tila bead measures 5 mm by 5 mm and sits about 1.9 mm thick, with two parallel holes running through the flat face at roughly 0.8 mm in diameter. That flat, two-hole square is the defining feature of the Tila shape, and it is why Tila bracelets look like a stacked mosaic instead of a strand of round beads.
Miyuki launched the Tila bead in the early 2000s as a variation on its Delica line, and the shape caught on fast with bracelet and loom-work designers. Instead of one center hole like a round seed bead, each Tila has two holes set side by side near the top edge, which is what lets the beads sit flush against their neighbors and lie flat rather than roll.
What Sizes Does the Tila Bead Family Come In?
Tila beads come in three official Miyuki sizes plus a wider "Tila-style" category from other makers. Full Tila is 5 mm x 5 mm x 1.9 mm, Half Tila is 5 mm x 2.3 mm x 1.9 mm, and Quarter Tila is 5 mm x 1.2 mm x 1.9 mm. All three share the same 1.9 mm thickness and 0.8 mm hole size, which is exactly why they combine so well in one piece.
| Bead | Dimensions | Holes | Typical use |
|---|---|---|---|
| Full Tila | 5 mm x 5 mm x 1.9 mm | Two, 0.8 mm, parallel | Main body of the bracelet |
| Half Tila | 5 mm x 2.3 mm x 1.9 mm | Two, 0.8 mm, parallel | Fills gaps, adds accent rows |
| Quarter Tila | 5 mm x 1.2 mm x 1.9 mm | Two, 0.8 mm, parallel | Thin accent lines, edging |
| Tila-style (other brands) | Varies, close to 5 mm x 5 mm | Usually two, size varies | Budget alternative, check spec before mixing |
Half Tila and Quarter Tila are not separate products so much as full Tila beads cut down. A Half Tila is literally half the width of a full one, and a Quarter is a quarter of the width, which is why a row of two Half Tilas takes up the same length as one Full Tila. Designers use that math to fill in awkward gaps in a pattern without breaking the flat, flush look.
One term worth knowing: "Tila-style" beads. Some manufacturers sell flat, two-hole square beads that are not genuine Miyuki. They can look nearly identical on a shelf, yet the size, hole placement, and glass quality can differ enough to throw off a pattern built around true Miyuki measurements. Mack & Rex sells authentic Miyuki-made Tila beads, sized and sorted so a pattern built for 5 mm x 5 mm holds up bead for bead.
Why Do Tila Beads Sit Flush Against Each Other?
Tila beads sit flush because the two parallel holes run near the top edge instead of through the center. That placement lets each flat face rest directly against the next bead's flat face with almost no gap, so a finished bracelet reads as one continuous tile surface rather than a string of separate beads.
Compare that to a round seed bead, which has a single hole dead center. Round beads naturally leave small triangular gaps between each other no matter how tight the tension. A Tila's square profile and off-center hole pair close that gap almost entirely. Stack twenty Tilas edge to edge and you get a clean, glassy mosaic look with barely a sliver of cord visible.
That flush fit is also why cord choice matters more with Tilas than with round beads. Too loose a cord and the beads twist out of alignment, breaking the flat look. Too tight and the bead edges cannot seat against each other properly. Getting the tension right is part craft, part patience.
How Many Tila Beads Do You Need for a Bracelet?
Most adult stretch bracelets take 28 to 38 full-size Tila beads in a single strung row, depending on wrist size. Since each Tila is 5 mm wide edge to edge, the math is simple: divide the finished bracelet length in millimeters by 5 to get a rough bead count, then round down slightly to leave room for the knot.
| Wrist size | Typical finished bracelet length | Approx. Tila beads needed |
|---|---|---|
| Kids / XXS | ~5.5 in (140 mm) | 26-28 |
| Small | ~6.0 in (152 mm) | 29-30 |
| Medium | ~6.5 in (165 mm) | 32-33 |
| Large | ~7.0 in (178 mm) | 35-36 |
| XL / Plus | ~7.5-8.0 in (190-203 mm) | 37-40 |
These are estimates, not a formula carved in stone. Real bracelets lose a few millimeters to the double knot, and elastic cord adds its own slight stretch once it is on a wrist. A safe habit: string a few extra beads loose on the cord, wrap it around the wrist before tying off, and trim to the count that actually sits right rather than trusting the math alone.
Does the Bead Count Change If You Mix in Spacers or Accents?
Yes, mixing bead types changes the count fast. Two Half Tilas fill the same 5 mm of length as one Full Tila, so swapping in an accent row of Half Tilas roughly doubles the piece count for that section without changing the bracelet's finished length. Round spacer beads or seed beads worked in between Tilas add their own width on top, which shortens how many Tilas fit in the same overall length.
This is where a lot of first-time bracelet makers get their count wrong. They order a strand of Tila beads sized for a 7-inch bracelet, then add a few round accent beads between each Tila and end up short by the time they reach the clasp. If a pattern calls for spacers, order a few extra Tilas beyond the base estimate so a gap in supply does not stall the project.
A Note on Safety When Kids Are Crafting
Tila beads are small enough to be a choking hazard, and that goes for the full, Half, and Quarter sizes alike. If kids are stringing beads with you, keep an adult at the table the whole time, and keep loose beads away from children under three or anyone who still mouths small objects. Loose beads and kits are craft supplies, not toys, and they are not sized or marketed for very young children.
Where Can You Shop Tila Beads Sized Right for Your Project?
Mack & Rex carries genuine Miyuki Tila beads in full, Half, and Quarter sizes, sold as loose mixes, themed color packs, and DIY bracelet kits with the elastic cord already matched to the bead holes. Every listing states the real gram weight and approximate piece count on the product page, so you can size a project before you buy instead of guessing.

FAQ: Tila Bead Size and Bracelet Counts
What size are Tila beads?
A standard Miyuki Tila bead measures 5 mm by 5 mm and is about 1.9 mm thick, with two parallel holes running through the flat face at roughly 0.8 mm in diameter. That flat square shape is what sets Tilas apart from round seed beads.
How many Tila beads fit on a 7-inch bracelet?
A 7-inch (about 178 mm) bracelet strung edge to edge in a single row of full-size Tila beads takes roughly 35 to 36 beads. Add a clasp or knot allowance and the real count usually lands a bead or two under that.
What is the difference between Tila, Half Tila, and Quarter Tila?
Full Tila is 5 mm x 5 mm x 1.9 mm. Half Tila is 5 mm x 2.3 mm x 1.9 mm, and Quarter Tila is 5 mm x 1.2 mm x 1.9 mm. All three share the same thickness and 0.8 mm hole size, so they mix cleanly in one design.
Are all two-hole flat beads the same size as Miyuki Tila?
No. Tila-style beads made by other manufacturers can run slightly larger or smaller than genuine Miyuki Tila, and hole spacing sometimes differs enough that patterns designed for one do not line up in the other. Check the listed millimeter size before mixing brands in the same bracelet.
Do bigger wrists just need bigger Tila beads?
No, the bead size stays the same. A bigger wrist just needs more beads strung in a row, since Tila beads come in one standard size and length is added by adding beads, not by sizing up the bead itself.
