My spouse is legally blind; I’m not. How does this impact our standard deduction on a joint return?

The additional standard deduction amount for blindness applies per person. If one spouse is blind, the couple’s standard deduction is increased by one additional amount for a married person ($1,300 on a 2020 return). If both spouses are blind, the additional standard deduction amount on a 2020 return is $2,600 ($1,300 + $1,300). The additional standard deduction amount for a married person who is blind in 2021 is $1,350.
