When renovating or building a house, choosing the correct Exterior Door size is a critical step. The door must fit correctly not only in terms of dimensions, but also in terms of materials, frame, swing, and design style. Below is a detailed guide to what “standard exterior door size” typically means, key measurements, variations, and what to look for when choosing a door. At the end, a word on ARTY from Yihedoor as an option.

Standard Dimensions: What You’ll Usually Find

Here are the most common dimensions for single exterior doors in residential buildings:

Double Doors

For double exterior doors, the height often remains around 80 in, but the width is doubled or increased accordingly:

• Standard double exterior widths: 60 in, 64 in, 72 in etc.

• Often used for grand entrances or where design aesthetics call for a wider opening.

Variations & Special Cases

While the above are common, there are many variations depending on style, architecture, building codes, and homeowner needs.

• Older homes may have non-standard sizes, sometimes narrower or with different heights.

• Modern and luxury homes often use taller doors (96 in or more) or wider single/pivot doors.

• Accessibility requirements (e.g. ADA standards) may require a minimum clear width. Many doors are built or chosen to accommodate wheelchair access, often 36 in wide.

• Rough opening (i.e. the framing / space in which the door + frame fits) must be larger than the door slab itself — typically an extra 2-2.5 in width, about 2 in height.

How to Measure Properly

To ensure your new exterior door fits properly, these steps help avoid mistakes:

1. Measure door slab width: measure in three places (top, middle, bottom) and use the smallest.

2. Measure height: from floor (or threshold) to top of the opening, again in multiple spots.

3. Measure thickness: especially if replacing slab only; frames, thresholds, weatherstripping all add up.

4. Measure rough opening: this includes space for the jamb/trim/frame; you may need to account for shimming, weatherproofing.

5. Check swing direction: inside or outside swing, hinge side. This affects how the door fits relative to walls, stairs, or pathways.

Why Standard Sizes Matter

• Cost efficiency: Standard sizes are produced in greater volume, cheaper materials and labour.

• Availability: Easier to get replacement doors in stock.

• Simpler installation: Less need to modify framing significantly.

• Aesthetic consistency: Matching doors for the same house or neighborhood often follow similar proportions.

Introducing ARTY by Yihedoor

Yihedoor is a manufacturer offering a range of exterior doors. Their ARTY line is one kind of design/style under their exterior door category. Here’s what makes ARTY noteworthy:

• Style-options: ARTY doors are typically designed with aesthetics in mind, balancing decorative design features with durability.

• Material & build quality: Yihedoor’s exterior doors (including ARTY) tend to use solid materials suitable for external use (weather-resistant, secure).

• Size flexibility: While standard sizes are the most common, ARTY doors can often be customized (or you can find different standard widths & heights) to match your home’s specific opening. Because Yihedoor focuses on a full exterior door range, ARTY benefits from that flexibility.

Summary

• The most standard exterior door size is 36 in width × 80 in height × 1¾ in thickness.

• Other common widths include 30 in, 32 in, especially in older or secondary doors.

• For newer or upscale homes, heights of 84 in or 96 in and wider doors are more common.

When selecting a door, measure carefully, think about rough opening, swing direction, and whether you want standard or custom sizes. If you want a door that blends style and durability, ARTY from Yihedoor is worth considering.
