The Length Question Everyone Asks
When you're browsing our lash range, one of the first choices you'll face is length. Our two most popular options are 12mm and 14mm — and while that 2mm difference might sound tiny, it makes a surprisingly noticeable difference to the final look.
In this guide, we'll explain exactly what that difference looks like in practice, which eye shapes and occasions each length suits, and how to decide which one to try first.
What Does Lash Length Actually Mean?
Lash length refers to the length of the longest lash fibres on the ribbon, measured in millimetres. Most lash ribbons are multi-length — meaning the fibres vary across the band to create a natural, tapered effect. The stated length (12mm or 14mm) is the maximum length at the longest point, usually towards the outer corner.
12mm Lashes: Natural, Everyday Elegance
12mm is our most popular length, and for good reason. It's the sweet spot between natural and noticeable — long enough to make a real difference, but subtle enough to wear every day without looking overdone.
12mm is ideal if you:
- Are new to DIY lashes and want something that looks natural
- Have smaller or more almond-shaped eyes
- Prefer a "your lashes but better" effect
- Want lashes you can wear to work, brunch, or everyday occasions
- Have hooded eyes — longer lashes can sometimes get lost under the hood, making 12mm a smarter choice
- Are applying a half lash to the outer corner for a subtle lift
The look:
Soft, fluttery, and polished. People will notice your eyes look amazing — they just won't necessarily clock that you're wearing lashes. Perfect for that effortless, put-together look.
14mm Lashes: Glamorous, Head-Turning Drama
14mm lashes are for when you want to make a statement. The extra length adds visible drama and a more defined, glamorous finish. They're still very wearable — just bolder.
14mm is ideal if you:
- Have larger or more prominent eyes with plenty of lid space
- Love a full, dramatic lash look
- Are dressing up for a special occasion, night out, or event
- Already wear lashes regularly and want to level up
- Have deep-set eyes — the extra length helps lashes stand out more
The look:
Bold, glamorous, and undeniably lash-forward. You'll definitely get compliments. These are the lashes people notice.
Which Length Suits Your Eye Shape?
| Eye Shape | Recommended Length | Why |
|---|---|---|
| Hooded eyes | 12mm | Longer lashes can disappear under the hood |
| Almond eyes | 12mm or 14mm | Both lengths work beautifully |
| Round eyes | 12mm (half lash) | Outer corner placement elongates the eye |
| Deep-set eyes | 14mm | Extra length helps lashes project forward |
| Monolid eyes | 12mm | Natural length blends more seamlessly |
| Upturned eyes | 12mm or 14mm | Either works — choose based on occasion |
Half Lash vs Full Lash: Does Length Choice Change?
Yes, slightly. If you're applying a half lash to the outer corner only, 14mm can look stunning even on smaller eyes because the length is concentrated at the outer edge, creating a cat-eye effect. If you're going for a full lash, 12mm tends to be more universally flattering.
Our Recommendation
If you're unsure, start with 12mm. It's more forgiving, more versatile, and easier to wear confidently while you're finding your lash style. Once you've got the hang of application and know what you like, 14mm is a brilliant next step for special occasions.
