How Wide is a 2 Car Driveway: And Why Do Squirrels Always Cross It Diagonally?

When it comes to designing or renovating a home, one of the most overlooked yet crucial aspects is the driveway. Specifically, the width of a two-car driveway is a topic that often sparks curiosity and debate. How wide should it be? Is there a standard measurement? And why, oh why, do squirrels always seem to cross it diagonally, as if they’re auditioning for a nature documentary? Let’s dive into the multifaceted world of driveway dimensions, exploring practical considerations, aesthetic choices, and the occasional squirrel-related tangent.


The Standard Width of a 2 Car Driveway

The most common width for a two-car driveway in the United States is 20 to 24 feet. This range allows enough space for two vehicles to park side by side comfortably, with a little extra room for opening car doors without scratching the paint on your neighbor’s prized sedan. However, this measurement isn’t set in stone. Factors such as local building codes, the size of the vehicles you own, and even the slope of your driveway can influence the ideal width.

For example, if you drive a pair of compact cars, a 20-foot driveway might suffice. But if your garage houses two SUVs or trucks, you might want to lean toward the 24-foot mark—or even wider. After all, nobody wants to play a game of vehicular Tetris every time they pull into their driveway.


Practical Considerations for Driveway Width

1. Vehicle Size and Accessibility

Modern vehicles are getting bigger, and so are driveways. A standard sedan might only need about 8 feet of width, but an SUV or truck can easily require 9 to 10 feet. Add in a few extra feet for maneuvering space, and suddenly that 20-foot driveway feels a bit cramped.

2. Local Building Codes

Before you start measuring and marking, check your local building codes. Some municipalities have specific requirements for driveway width, especially if your property is near a busy street or in a densely populated area. Ignoring these regulations could lead to fines or, worse, having to redo your driveway entirely.

3. Slope and Drainage

A steeply sloped driveway might require additional width to ensure safe entry and exit. Additionally, proper drainage is essential to prevent water from pooling and causing damage. A wider driveway can help distribute water more evenly, reducing the risk of erosion or flooding.

4. Aesthetic Balance

While functionality is key, aesthetics also play a role. A driveway that’s too wide can overwhelm your home’s façade, while one that’s too narrow might look out of place. Striking the right balance between form and function is crucial.


The Squirrel Conundrum

Now, let’s address the elephant—or rather, the squirrel—in the room. Why do these furry little creatures insist on crossing driveways diagonally? Some theories suggest it’s a survival tactic, allowing them to cover more ground while minimizing exposure to predators. Others believe it’s simply a matter of efficiency, as diagonal paths are shorter than straight ones. Whatever the reason, it’s a phenomenon that adds a touch of whimsy to an otherwise mundane topic.


Beyond the Basics: Creative Driveway Ideas

If you’re feeling adventurous, why not think outside the box when designing your driveway? Here are a few ideas to inspire you:

1. Two-Tone Paving

Using contrasting materials or colors can create a visually striking driveway. For example, combining brick and concrete adds texture and character.

2. Integrated Lighting

Solar-powered or LED lights along the edges of your driveway not only enhance safety but also create a welcoming ambiance.

3. Green Spaces

Incorporating strips of grass or gravel between paving stones can soften the look of your driveway and improve drainage.

4. Curved Designs

A gently curved driveway can add a sense of elegance and make your property stand out from the rest.


Frequently Asked Questions

1. Can a 2 car driveway be less than 20 feet wide?

While it’s possible, a narrower driveway might make parking and maneuvering difficult, especially with larger vehicles.

2. How much does it cost to widen a driveway?

Costs vary depending on materials and labor, but widening a driveway can range from $5 to $15 per square foot.

3. Do I need a permit to widen my driveway?

In most cases, yes. Check with your local building authority to ensure compliance with regulations.

4. What’s the best material for a driveway?

Concrete, asphalt, and pavers are popular choices, each with its own pros and cons in terms of durability, cost, and maintenance.

5. Why do squirrels cross driveways diagonally?

While there’s no definitive answer, it’s likely a combination of survival instinct and efficiency. Or maybe they just enjoy keeping us guessing.


In conclusion, the width of a two-car driveway is more than just a number—it’s a balance of practicality, aesthetics, and even a little bit of wildlife whimsy. Whether you’re building a new driveway or renovating an existing one, taking the time to consider all these factors will ensure a result that’s both functional and visually appealing. And who knows? Maybe you’ll even solve the mystery of the diagonal-crossing squirrels along the way.
