Kiln Size Calculator

Find the perfect kiln size for your pottery projects and studio needs

Not sure what size kiln you need? Our calculator will help you determine the right kiln size based on your typical pottery pieces and firing frequency.

Calculate Your Kiln Needs

What do you typically make?

More frequent firing means you can use a smaller kiln since you'll fire more batches. Less frequent firing requires a larger kiln to accommodate all your pieces at once.

Your practice level affects the growth buffer we add to your kiln size. More professional practices get larger buffers to accommodate business growth and increased production.

Kiln Buying Tips

Important considerations when choosing your kiln

1

Consider Your Space

Make sure you have adequate space and proper ventilation. Kilns need clearance on all sides and proper electrical connections.

2

Electrical Requirements

Larger kilns require 240V electrical connections. Also beware of buying a used kiln that is 208V since that requires an industiral electrical panel. Check if your space can accommodate the electrical needs of your chosen kiln.

3

Think About Growth

Consider your future needs. It's often better to buy slightly larger than you currently need to accommodate growth in your pottery practice.

4

Firing Efficiency

Smaller kilns heat up faster and use less energy per firing, but larger kilns are more efficient when firing many pieces at once.

5

Budget Considerations

Factor in not just the kiln cost, but also installation, electrical work, and ongoing operating costs like electricity and kiln furniture.

6

Kiln Furniture

Don't forget to budget for kiln shelves, posts, and other furniture needed to properly load and fire your kiln.
