Whether you are renovating an older home, building from the ground up, or sourcing doors for a multi-unit development, one dimension keeps appearing in specifications and order sheets: the 28 x 80 entry door. But what makes this size so common, and how do you make sure you are choosing the right door — not just in dimensions, but in material, construction, and long-term performance?
A 28 x 80 entry door refers to a door slab that is 28 inches wide and 80 inches (6 feet 8 inches) tall. This is one of the most frequently specified sizes for interior passage doors and secondary exterior entrances, such as side entries, utility room access, and basement walkouts.
While it is slightly narrower than the more commonly discussed 36-inch entry door, the 28-inch width serves a practical purpose in tighter floor plans where wall space is at a premium — think laundry rooms, pantries, or rear service entries in residential projects.
Understanding standard entry door sizes helps you plan your project with confidence. Here is how the 28 x 80 compares to other commonly manufactured dimensions:
One of the advantages of working with professional entry doors manufacturers is the ability to order custom sizes alongside standard dimensions. Not every opening matches a stock size perfectly, and a manufacturer with flexible production capabilities can accommodate project-specific requirements without compromise.
The material of your entry door determines not just how it looks, but how it performs over years of exposure to sun, rain, humidity, and daily use.
Wood doors offer classic warmth and traditional appeal. However, they demand regular maintenance — sanding, sealing, and repainting — to prevent warping, rotting, or swelling in humid conditions. In coastal or tropical climates, wood doors tend to have a noticeably shorter service life.
Steel doors provide strength and security at a relatively affordable price point. The downside is that steel is susceptible to rust and dents. A scratch that reaches bare metal can become a corrosion problem within a single rainy season if not addressed.
An aluminum entry door strikes a compelling balance. High-grade aluminum — particularly 6060-T66 alloy with wall thicknesses from 1.8mm to 2.5mm — resists corrosion naturally, maintains its structural integrity for decades, and requires virtually no maintenance beyond occasional cleaning. For projects in the Middle East, Southeast Asia, coastal Australia, or anywhere with high heat and humidity, aluminum has become the material of choice among architects and specifiers.
Beyond material, several engineering details separate a well-built entry door from a commodity product. When evaluating a modern entry door for your project, pay attention to the following:
A thermal break — typically a PA66GF25 polyamide strip reinforced with glass fiber — sits between the interior and exterior aluminum profiles. This barrier dramatically reduces heat transfer, keeping indoor spaces cooler in summer and warmer in winter. It also prevents condensation from forming on the interior frame surface, which is especially important in air-conditioned buildings.
The handles, hinges, locks, and multi-point locking systems are the components you interact with every day. Premium manufacturers partner with established European hardware brands such as ROTO (Germany), Winkhaus (Germany), Wehag (Germany), and CMECH. These components are engineered for tens of thousands of operation cycles and maintain smooth, precise function year after year.
An entry door takes the brunt of sun exposure. Powder coating and PVDF coating technologies protect the aluminum surface from fading, chalking, and corrosion. Standard color options such as Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee suit most architectural styles, while custom color matching is available for projects with specific design requirements.
If your entry door includes glazing, the glass package matters as much as the frame. Double or triple insulated glass with Low-E coatings, argon gas filling, and laminated security options can be specified depending on climate, security needs, and energy code requirements.
Whether you need one custom-sized 28 x 80 entry door or a container load for a residential development, the right manufacturing partner should offer more than just a product catalog.
Look for a supplier with a substantial production base — at least tens of thousands of square meters of factory space indicates the capacity to handle both volume orders and custom projects. A manufacturer that operates multiple production centers can also offer logistical flexibility.
ALPES, for example, operates from a 100,000 m² manufacturing facility with two production centers in Foshan and Zhaoqing, Guangdong, China. The company has completed window and door projects for luxury villas in Saudi Arabia, Dubai, and Australia, demonstrating experience across diverse climate zones and architectural styles.
When you reach out for a quote, expect to discuss: your project location and climate, the door dimensions and configuration, preferred material and finish, hardware requirements, glass specifications, and your project timeline. A serious manufacturer will provide detailed technical drawings and performance data — not just a price.
Even the best door will underperform if installed incorrectly. For a 28 x 80 entry door, make sure the rough opening provides adequate clearance — typically 2 inches wider and 2.5 inches taller than the door slab — to allow for proper shimming, leveling, and insulation around the frame.
Pay special attention to the threshold and weatherstripping. An exterior entry door must seal effectively against water, drafts, and insects regardless of its size. Multi-point locking systems that engage at the top, bottom, and sides of the door frame provide a tighter seal than a single deadbolt alone.
