Authentic street taco tortillas typically range from 8cm to 14.5cm in diameter. These smaller sizes ensure the filling remains the focal point while maintaining the structural integrity of the tortilla.
The specific diameter you choose determines the balance between the corn masa and the filling, shifting the experience from a light snack to a substantial meal.
Standard street taco sizing
For a traditional Mexican street experience, diameters of 8cm, 11cm, and 12.5cm are the most appropriate. These sizes allow diners to eat multiple tacos with varying fillings without becoming overly full. Using smaller tortillas prevents the masa from overwhelming the palate and keeps the taco easy to handle.
| Diameter | Recommended Use |
|---|---|
| 8cm | Miniature tacos or appetisers |
| 11cm – 12.5cm | Traditional street tacos |
| 14.5cm | Substantial tacos or small wraps |
The impact of nixtamalization on size
At La Tortillería, we stone-grind Australian-grown corn fresh each day rather than using instant masa harina. This traditional nixtamalization process creates a tortilla that is hot and floppy, meaning even a small 11cm tortilla has the malleability to fold without cracking. When customers at our Kensington tortilleria substitute supermarket corn tortillas, they often find them too stiff or prone to breaking regardless of the size.
Matching tortilla size to fillings
The size of your ingredients must correspond with the diameter of your tortilla for easy eating. For example, when preparing zucchini and sweet potato tacos, dicing vegetables into 1cm cubes ensures they sit securely within a standard corn tortilla. Heavier proteins like slow-cooked carnitas or large chunks of grilled fish typically perform better on a 14.5cm or 16cm base to prevent the filling from spilling.
Finding authentic tortillas in Australia
Finding authentic nixtamalized corn tortillas can be difficult in mainstream Australian supermarkets like Coles or Woolworths. We make these available through our own store, our online shop, and a selection of independent grocers across the country. Our tortillas are gluten-free, vegan, and FODMAP friendly, though we recommend consulting a medical professional or dietitian regarding specific dietary requirements.
