Homemade tortillas are a staple in many kitchens, but one common frustration is that they often shrink after being pressed. This can be confusing, especially when you’ve carefully measured your dough balls and pressed them to the perfect size, only to watch them contract before or during cooking. Understanding the reasons behind this phenomenon is crucial for anyone aiming for consistently round, pliable, and full-sized tortillas.
In this article, we’ll explore the main causes behind tortilla shrinkage after pressing, practical solutions to prevent it, and tips for achieving the best results whether you’re making corn or flour tortillas. We’ll also highlight expert advice and link to additional resources for those looking to master their tortilla-making process from start to finish.

Main Reasons Tortillas Shrink After Pressing
There are several factors that contribute to tortillas shrinking after being pressed. Recognizing these can help you adjust your technique and ingredients for better results.
Gluten Development in Flour Tortillas
For flour tortillas, gluten formation is a primary cause of shrinkage. When wheat flour is mixed with water and kneaded, gluten strands develop, giving the dough elasticity. If the dough is overworked or not rested enough, it tends to spring back after pressing, resulting in smaller, thicker tortillas.
- Over-kneading makes the dough too elastic.
- Insufficient resting doesn’t allow gluten to relax, causing the dough to contract.
Moisture Content and Masa Consistency
For corn tortillas, the masa (dough) consistency is key. If the dough is too dry, it will shrink and crack after pressing. On the other hand, overly wet dough can stick to the press and tear.
- Dry masa contracts and becomes brittle.
- Proper hydration keeps tortillas pliable and helps them hold their shape.
Temperature and Dough Handling
The temperature of both your dough and your kitchen can affect shrinkage. Cold dough is stiffer and more likely to contract, while dough at room temperature is more relaxed. Additionally, handling the dough too much or pressing it repeatedly can increase elasticity, causing it to shrink.
How to Prevent Tortilla Shrinkage
Preventing shrinkage starts with understanding the science behind your dough and making a few simple adjustments to your process.
Letting the Dough Rest
One of the most effective ways to minimize shrinkage is to let your dough rest before pressing. For flour tortillas, after kneading, cover the dough and let it sit for at least 20–30 minutes. This allows the gluten to relax, making the dough easier to press and less likely to spring back.
Adjusting Hydration for Corn Masa
For corn tortillas, achieving the right hydration is essential. The masa should feel soft and slightly tacky, but not sticky. If it feels dry or cracks when pressed, add a small amount of water and knead until the texture is smooth.

Pressing Techniques and Tools
Using a quality tortilla press and the right pressing technique can also help reduce shrinkage. Apply even, gentle pressure rather than forcing the dough. Avoid pressing the same tortilla multiple times, as this can make it more elastic.
Expert Tips for Consistent Tortilla Size
Achieving tortillas that stay the same size after pressing is possible with a few expert strategies:
- Divide dough evenly: Use a kitchen scale to portion dough balls for uniform tortillas.
- Keep dough covered: Prevent drying out by covering dough balls with a damp towel while you work.
- Press once: Avoid re-pressing, which can activate gluten or toughen masa.
- Cook immediately: Place pressed tortillas directly onto a hot griddle to set their shape.

Common Mistakes That Lead to Shrinkage
Even experienced cooks can run into issues that cause tortillas to shrink. Here are some frequent pitfalls:
- Not resting the dough: Skipping this step leads to elastic, shrinking tortillas.
- Pressing cold dough: Dough should be at room temperature for best results.
- Using too much flour or masa harina: Excess dry ingredients make the dough stiff and prone to shrinking.
- Over-handling: Repeated pressing or stretching increases elasticity.
Maintaining Your Tortilla Press and Workspace
Clean equipment is essential for consistent results. If you use a cast iron press, proper sanitation between sessions prevents dough from sticking and ensures smooth pressing. For best practices, see our guide on how to sanitize a cast iron press.
Additionally, using the right liners (such as parchment or plastic) in your press can help prevent sticking and tearing. For those curious about alternatives, our article on can you use wax paper in a tortilla press discusses the pros and cons of different liner materials.
Frequently Asked Questions
Why do my flour tortillas keep shrinking even after resting the dough?
If your flour tortillas still shrink after a proper rest, it’s possible the dough was over-kneaded or not hydrated enough. Try reducing kneading time and ensuring the dough is soft and slightly tacky before resting. Also, avoid adding too much flour during shaping.
Can I fix tortillas that have already shrunk?
Once a tortilla has contracted, it’s difficult to stretch it back out without tearing. However, you can use the experience to adjust your dough hydration and resting time for the next batch. For now, use the smaller tortillas for tacos or snacks.
Does the type of tortilla press affect shrinkage?
While the press itself doesn’t directly cause shrinkage, a sturdy, heavy-duty press can help you achieve even thickness and shape, which minimizes the risk. Lightweight or uneven presses may require extra force, which can overwork the dough and contribute to contraction.
What’s the best way to keep tortillas soft and pliable after cooking?
Stack cooked tortillas in a clean kitchen towel or tortilla warmer immediately after cooking. This traps steam and keeps them soft. Avoid leaving them uncovered, as they will dry out and become brittle.
Conclusion
Understanding the causes behind tortilla shrinkage after pressing—whether it’s gluten development, dough hydration, or handling techniques—can help you achieve consistently round, soft, and full-sized tortillas. By letting your dough rest, adjusting hydration, using proper pressing techniques, and maintaining your equipment, you’ll minimize shrinkage and enjoy better results every time.
