As pasta consumption increases around the world, so too does the variety of pasta types. With an estimated 350 pasta types made in Italy, it’s not surprising that some of them look similar.
Two commonly confused pasta shapes are ziti and penne. They’re both cylindrical-shaped, hollow pasta that often get used interchangeably. But, they have subtle differences and each has specific uses in Italian cooking. This guide explains the difference between ziti and penne pasta. By the end of this page, you’ll never mix them up again.
What’s the difference between ziti and penne pasta?
Ziti and penne are both varieties of pasta that are shaped like tubes. Penne has diagonal ends like a quill pen, while ziti has straight ends like a pipe. Each pasta has a similar taste and texture, so it’s fine to substitute one for the other in recipes.
- Ziti was first made in Campania, Italy. Its name originated from the word zito, which can be translated as “bridegroom”. Pasta is traditionally eaten at weddings which explains the association.
- Penne also originated in Campania and has a diagonal edge that looks a lot like a quill tip pen. It’s this shape that resulted in the name penne, which translates to pens.

The average Italian consumes 26 kg of pasta each year.
Comparing penne and ziti
The differences lie in the shape; these subtle contrasts mean that each works better in certain dishes. Let’s look at these differences:
The ends: each end of penne pasta is cut diagonally which differs from the straight cut ends of ziti. The ends of ziti look like a tube.
The length: penne measures about 1½ inches whereas ziti ranges from 1½ – 3 inches. It can also be sold in 10″ pieces or even longer which are broken into pieces when cooked.
The Diameter: Ziti is ¼ inch whilst penne is larger at ½ inch.
Their variations: Penne can be smooth or ridged whereas ziti is usually smooth.

Penne has diagonal ends. Ziti looks like a tube.

How to use each pasta like a true Italian
In Italy, penne is traditionally boiled for 12 minutes until al dente then combined with sauce in a shallow pan.

Penne is delicious used in a ragu.
Ziti is often cooked for only 5-8 minutes until it starts to soften but it still undercooked. It then gets added to a casserole dish with cheese and baked until deliciously browned on top. This dish is a lot like Mac n Cheese.
Penne pairs with
Although penne pairs well with almost any sauce, it works brilliantly with chunky sauce, big hunks of meat, and vegetables. Oil-based or cream sauces both complement penne well.
Ziti Pairs with
Similar to penne, ziti pairs well in baked dishes with chunky sauces and meat. Ziti also makes a smart addition to stir-fries and salads.
Bonus Tips
- Pasta with ridges allows the sauce to stick to it better than smooth pasta.
- You’ll find it’s easier to overcook ziti. Penne is thicker and can tolerate longer cooking times.
