We're glad you asked! We have advice about this very subject.

Pendant size is determined by taking the width (not length) of your island in inches and subtracting 12. The number you get is a good maximum size for a pendant light.

We recommend spacing pendants about 2 feet apart, so with your 8 foot island you could definitely go for 3 pendants. If you do choose 3, choose ones that are a bit smaller than the maximum size per pendant as mentioned above. If you go for 2, you could pick out larger pendants (which is a popular look these days), more towards that maximum size per pendant.

Please let me know if you have any questions or want me to pick out some item recommendations for you!
