Do you want ALL the particles smaller, or do you want the most obtrusive ones disabled? These packs are for you! The 'no obtrusive' option disables block breaking, mob potion, food eating, and explosion particles. The better villager particles pack is best for villager station connecting status

No Obtrusive:

When the particles are removed, you can see yourself and the mobs without any potion effects in the way. Note that this makes lingering potion Area Effect Clouds invisible, but not dragon's breath.

Off:

On: 

I also disabled explosion particles which are sometimes oversized when wither skulls and shulker bullets hit the targets and walls. There is no screenshot preview for it though

Tiny particles: 

Big villager particles:

• The limit of how much particles can be present at once is changed from 25 to 2000.
• 50% transparency
• Can be seen through walls
• Display time is 5 seconds exactly
