Looks like if you want something smaller you will need to replace the cranks too

how many teeth is that? 5 bolt chainrings get smaller.

Likely a 110 BCD chainring, the typical way to measure for determining BCD would be between two adjacent bolt holes. It also probably says it on the chainring somewhere.

Measure from the chainring bolt to the crank bolt in the middle and multiply it by 2. that way you have the correct bcd.

Measure from one bolt to an adjacent bolt and multiply by 1.7. Round to the nearest number that’s listed in a BCD chart.
