What is the spacing of tomatoe plants??

What variety? Determinate or indeterminate? Thank you.

Are you using tomato cages, t-posts, letting them sprawl on the ground?

According to the "experts" minimum spacing is 2 - 3 ft but, if you put tomato plants on a grid 2 - 3 ft apart, I dare you to pick them.

I usually grow indeterminents, place them 2 - 3 ft. apart, in cages, in a single depth row and they are hard to pick.

Crowding also encourages all sorts of problems: mildew, fungus, bugs... If you have any amount of humidity, space them well.

I plant my heirloom tomatoes in remesh cages 22" across and 6" apart. The 6" remesh makes it easy to reach in to prune suckers early and pick tomatoes later. Rebars pounded into the soil and attached to the cages hold them up in the strongest storms. The remesh cages are 25 years old and still holding strong. Best tomato cages ever!
