As demonstrative pronouns, este is masculine , esta is feminine, and esto is neuter. The first two are fairly clear, since they always refer to nouns with matching gender. However, unlike many other languages, Spanish has no nouns with neuter gender.
The este/esta/esto (this) trio is very similar to other trios like ese/esa/eso (that) and aquel/aquella/aquello (further away that), so it makes sense to learn them together. In all three of those trios, the first always refers to something masculine, the second is feminine, and the third is neutral.
