Condoms come in all shapes, sizes, and materials. Here are the variations you can get:
Material
Most condoms are made from latex or polyurethane. The latex ones are a little stronger, so they give slightly better protection from STIs and pregnancy. A very small amount of people are allergic to latex, though, so they use polyurethane ones.
Size
Condoms come in lots of different sizes. You can get longer or shorter or wider or narrower ones. If a packet of condoms says 'large' or 'small', this is usually talking about the width of the condom, not the length. Be honest! A condom that is too big may come off, and a condom that's too small might break. Most condoms that you buy in shops and vending machines will be a standard size.
Small condoms – recommended for a penis under 5 inches in length, or under 4 inches in girth (condom girth less than 3.9 inches)
Standard condoms – recommended for a penis between 5-7 inches in length, or 4-5 inches in girth (condom girth 4.0 - 4.39 inches)
Large condoms – recommended for a penis over 7 inches in length, or over 5 inches girth (condom girth 4.40+ inches)
