Main doors can come in a variety of designs, models, and types, and the best one for you will depend on your individual needs and preferences. Here are some popular options:

Solid wood doors: These doors are made from a solid piece of wood and offer a classic, traditional look. They are durable and can be stained or painted to match the interior of your home.

Fiberglass doors: These doors are made from a combination of fiberglass and other materials, and they offer the look of wood but with better insulation and resistance to the elements.

Steel doors: Steel doors are strong and durable, making them a popular choice for security-conscious homeowners. They can be painted or finished to match the look of your home.

Glass doors: Glass doors, either with or without frames, can add a modern touch to your home and also provide natural light.

Pivot doors: Pivot doors are hinged on a central point, rather than at the sides, and they swing open and closed in a unique way.

Dutch doors: Dutch doors are split into two sections, with the top half able to open independently from the bottom half. This design provides the ability to let in light and air while keeping the bottom half closed for security.

Sliding doors: Sliding doors can provide an attractive alternative to traditional hinged doors, and they can be especially convenient in homes where space is limited.

There are many other main door design options available, so it's best to consider your specific needs and preferences, as well as the overall style of your home, when choosing the right door for you
