.044 vs .046 Siding – Which Siding Should You Choose? 

Choosing the right siding for your home is crucial for its overall appearance, protection, and energy efficiency. When it comes to siding thickness, the terms .044 and .046 are commonly encountered. These numbers represent the gauge or thickness of the siding material. While the difference may seem small, it can significantly impact durability, appearance, and cost. In this guide, I’ll discuss the key distinctions between .044 and .046 siding, enabling you to make an informed decision that aligns with your specific needs and budget.

.044 vs .046 Siding

Side by Side Differences Between 0.044 and 0.046 Siding

The main difference between these two types of siding lies in their thickness, with .046 being slightly thicker than .044 (measured in mms). But this seemingly small difference can have a significant impact on several aspects of your siding. Let’s delve deeper:


Siding thickness directly correlates to its grade or quality level. 0.044 siding falls into the premium category, offering a good balance of durability and affordability. On the other hand, 0.046 siding is considered super or ultra-premium, representing the highest quality and most long-lasting option available.


Think of your siding as your home’s first line of defense. Here’s where the thickness advantage of .046 siding comes into play.

Thicker siding (.046 mm) is generally more durable and better able to withstand elements like wind, hail, and impact. The thicker material is stiffer and less prone to vibrating or “humming” in strong winds, keeping your home a quiet sanctuary during storms.


Rigidity refers to a material’s ability to resist bending or warping. Here’s a quick breakdown:

  • .044 – More flexible: This can be advantageous during installation, as it allows for easier maneuvering around corners and curves.
  • .046  mm- More rigid: This translates to a sturdier overall look and a higher resistance to dents and dings.  Think of it like the difference between a cardboard box and a well-built wooden crate.

Wider Color Selection

Ever dreamt of a deep charcoal or a dramatic midnight blue for your home’s exterior? Here’s where things get interesting.

Darker colored siding is typically only available in the thicker 0.046 or greater thicknesses. The reason? Thinner panels might not be rigid enough to support darker colors without warping or showing imperfections.

So, if your heart is set on a bold and dramatic color scheme, .046 siding might be your best bet.


As with most building materials, thicker siding comes at a higher cost. 0.046 siding is generally more expensive than 0.044 siding due to the increased material and manufacturing costs. However, this higher upfront cost may be offset by the enhanced durability and longevity of the thicker siding.

0.046 thick vinyl siding can cost around $4 per sq ft whereas, 0.044 thick, vinyl siding costs around $0.97 per square foot.

However, consider this: a thicker siding might last longer, potentially saving you money on replacements down the road. It’s a long-term investment!

Which One to Choose Between 0.044 and 0.046 Siding

The ultimate decision-making time is upon us. When deciding between .044 and .046 siding, there are several factors to consider, each as important as the next:

  • Climate and weather conditions: If you live in an area that’s prone to high winds, hail storms, or harsh weather in general, the thicker .046 siding might just be your knight in shining armor, providing better protection and durability.
  • Budget: Let’s be real; money talks. .044 siding is the more budget-friendly option, while 0.046 siding will put a bigger strain on your hard-earned cash.
  • Aesthetics: Some homeowners simply can’t resist the allure of a more substantial, beefier look – and that’s where the slightly thicker .046 siding comes into play, giving your home a more substantial and robust appearance.
  • Installation: Lighter .044 siding is a breeze to handle during installation, while the heftier 0.046 variety might require a bit more muscle (or additional support) to get the job done right.
  • Insulation and energy efficiency: The added thickness of .046 siding can contribute to better insulation properties, potentially helping you save some green on those pesky energy bills in the long run.

At the end of the day, the choice between .044 and .046 siding is a delicate balance between your specific needs, priorities, and budget. If durability trumps all else (especially in harsh climates), the thicker .046 siding might just be your knight in shining armor. But if you’re working with a tighter budget and don’t face extreme weather conditions, the trusty .044 siding could be a perfectly practical option.

End Notes

Remember, your siding is an investment that will protect your home for years to come. Taking the time to understand the differences between .044 and .046 siding will ensure you make the best choice for your needs and budget.

So, are you ready to give your home the ultimate makeover? With the right knowledge and a bit of planning, you can choose the perfect siding that will keep your home safe, stylish, and weatherproof for years to come.
