Imagine this scenario: It’s a bright, sunny afternoon, and you’re comfortably seated on your patio, sipping a refreshing, cold beverage, and basking in the warmth of the sun. However, as the day advances, the sun’s rays become too intense, and the heat becomes unbearable. Consequently, you retreat indoors, abandoning your beautiful outdoor space.

Does this situation sound familiar? Fortunately, it doesn’t have to be this way. With the installation of an aluminum patio cover, you can enjoy your outdoor space, irrespective of the weather conditions. But the question remains, how do you select the right size for your space? Let’s delve into this topic.

Understanding Your Space
The initial step in choosing the appropriate size of an aluminum patio cover is to comprehend your outdoor space.
Here are some steps to help you understand your space better:
- Take a comprehensive look at your patio.
- Identify its size and shape.
- Determine whether it’s a small square, a large rectangle, or an irregular shape.
Knowing the dimensions of your patio is crucial as it determines the size of the cover you’ll require.
Consider the case of John and Mary. They have a small, square patio where they love to enjoy their breakfast. However, the morning sun often makes it too hot to sit outside. They decided to install a 15′ x 15′ aluminum patio cover, providing just enough shade for their small space. Now, they relish their morning coffee outdoors, without the discomfort of the intense sun.
Standard Aluminum Patio Cover Sizes
Understanding standard patio cover dimensions helps you plan your project and budget accordingly. Here are the most common sizes available:
Small Patio Covers (Under 200 sq ft)
- 10′ x 10′ – Ideal for bistro tables or small seating areas
- 10′ x 12′ – Covers a 4-person dining set comfortably
- 12′ x 14′ – Popular for townhomes and smaller backyards
Medium Patio Covers (200-400 sq ft)
- 14′ x 16′ – Accommodates 6-person dining plus small lounge area
- 16′ x 18′ – Most popular size in the Okanagan for average-sized decks
- 16′ x 20′ – Excellent for outdoor kitchens with dining space
Large Patio Covers (400+ sq ft)
- 20′ x 20′ – Full outdoor living room and dining combination
- 20′ x 24′ – Accommodates large gatherings with multiple zones
- 24′ x 30’+ – Estate-sized covers for expansive outdoor living
Remember, these are standard sizes. Most aluminum patio cover manufacturers can create custom sizes to match your exact specifications.
How to Measure for a Patio Cover
Accurate measurements are essential for a proper fit. Follow these steps to measure your space correctly:
- Measure the projection (depth): This is how far the cover extends from your house. Measure from your exterior wall to where you want the cover to end.
- Measure the width: This is the length along your house wall. Consider how much of your patio or deck you want covered.
- Check ceiling height: Measure from the patio surface to where the cover will attach to your house. Minimum clearance is typically 7 feet.
- Note obstructions: Identify any windows, doors, vents, or utilities that might affect installation.
- Consider furniture layout: Allow extra space around furniture. A 6-person dining table needs approximately 12′ x 12′ of covered space.
Pro tip: Add 2-4 feet to your measurements on each side. This provides overhang protection from angled sun and wind-driven rain, making your covered space more usable throughout the day.
Customization is Key
One of the remarkable aspects of aluminum patio covers is their versatility.
Here are some customization options:
- Create a custom cover based on your unique specifications.
- Choose from pre-selected standard sizes.
This flexibility means you can get a cover that fits your patio perfectly, regardless of its size or shape.
For instance, Sarah has a large, rectangular patio that she uses for hosting parties. A standard size cover wouldn’t provide enough shade for her space. So, she opted for a custom-sized cover that extends the entire length and width of her patio. Now, her guests can enjoy the outdoor party, rain or shine.

Patio Cover Size and Cost: What to Budget
Understanding the relationship between patio cover size and cost helps you make informed decisions. Here’s what to expect for aluminum patio covers in the Okanagan:
| Size Category | Square Footage | Typical Installed Cost |
|---|---|---|
| Small | 100-200 sq ft | $4,000 – $8,000 |
| Medium | 200-400 sq ft | $8,000 – $15,000 |
| Large | 400-600 sq ft | $15,000 – $25,000 |
| Extra Large | 600+ sq ft | $25,000+ |
Costs vary based on:
- Roof style: Solid insulated panels cost more than lattice or open-beam designs
- Colour options: Custom colours may add 10-15% to the price
- Additional features: Integrated lighting, fans, or skylights increase costs
- Site conditions: Sloped lots or difficult access can affect installation costs
- Permits: Required in most Okanagan municipalities, typically $200-$500
Going Beyond the Patio
When installing an aluminum patio cover, you’re not confined to the size of your existing patio. You can choose a cover that extends beyond your patio, creating additional shaded space. This is a fantastic option if you have a large yard and want to create an expansive outdoor living area.
Mike and Lisa, for example, have a small patio but a large backyard. They wanted to create an outdoor dining and relaxation area that could accommodate their large family. They chose a 10′ x 20′ aluminum patio cover that extends beyond their patio, providing ample shaded space for their family gatherings. Now, their backyard is the go-to spot for family barbecues and get-togethers.
