### Ari akan ƙimar pixel

Idan kuna son lissafin yawan pixel na allonku, dole ne ku sani: ƙididdigar pixel a kwance da a tsaye da girman girman allo. Sannan amfani da wannan dabara, ko amfani da kalkuleta;)

$$d_p = \sqrt{w^2 + h^2}$$ $$PPI = \dfrac{d_p}{d_i} \ \$$ where

 $$w$$ shine ƙudurin faɗi a cikin pixels $$h$$ shine tsayin tsayi a cikin pixels $$d_p$$ shine ƙudurin silaid a cikin pixels $$d_i$$ girma ne mai inuwa a inci (wannan ita ce lambar da aka tallata a matsayin girman girman nuni)

Idan kanaso ka kara sani, ka duba wannan bidiyo mai ban mamaki Linus Tips a kasa.
