If you're like us, you love all things pumpkin. From pumpkin spice lattes to pumpkin pie, there's nothing this gourd can't make better. But have you ever wondered how many pumpkin seeds fit in a mason jar? We decided to find out.


We started with a standard 16 oz. mason jar and set to work filling it with pumpkin seeds. The first thing we noticed was that the seeds quickly began to stack up, making it difficult to estimate how many were actually in the jar. After about 15 minutes of carefully scooping and counting, we had our answer: 1,089 pumpkin seeds fit in a 16 oz. mason jar.

But what if you're not using a standard mason jar? What if you have a smaller or larger one? Not to worry—we've done the math for you. Here's how many pumpkin seeds fit in some of the most popular sizes of mason jars:

  • 16 oz.: 1,089 seeds
  • 32 oz.: 2,178 seeds

  • 128 oz.: 8,712 seeds
