Choosing The Correct Size Running Shorts: A Comprehensive Guide

Men's running shorts

Running is one of the best exercise variants you can take part in, something that goes back to human’s very early days as endurance-focused hunter-gatherers. It’s also one of the more affordable means of exercise, but it still pays to ensure you have the right equipment.

A handy water bottle, supportive footwear that helps your stride, and well-fitting running shorts from TCA can provide a much cleaner and safer running experience, helping you achieve optimal running.

TCA is a trusted authority in exercise shorts and training apparel. Our athletic-wear designers take special care to form clothes that both support and provide the full mobility you need to exercise correctly. 

We also ensure our products fit many unique body types, accounting for varied dimensions, sizes, and heights. Through this, our prized goal of inclusivity is achieved through every product we release to market. 

No matter your fitness level, you deserve a pair of 2-in-1 men's running shorts that fit comfortably and enhance your training performance.

When browsing running shorts, it’s important to look for a perfect fit. In this guide, we’ll discuss how to achieve that.

How To Choose The Correct Size Running Shorts

Selecting the right pair of running shorts is a crucial aspect of optimizing your comfort and performance during workouts. The vast array of options can be overwhelming, but by considering key factors, you can find the perfect fit for your running style.

  1. Length Matters: The length of your running shorts can significantly impact your comfort. Shorter inseams provide more freedom of movement and are suitable for warmer weather, while longer inseams offer additional coverage, making them a good choice for cooler temperatures or those who prefer more modesty. At TCA, we offer a range of inseam lengths for our exercise shorts for men allowing you to choose the fit that best suits your eye and comfortability.
  2. Fabric Composition: All of TCA’s running shorts are made with moisture-wicking and breathable fabrics. These materials help manage sweat and keep you cool during intense workouts. Additionally, seamless or flat-seam construction minimizes chafing and enhances overall comfort.
  3. Built-In Liners: Most of our running shorts come with built-in liners or compression shorts. These can provide added support, prevent chafing, and offer a modest option for those who prefer not to wear additional undergarments during their run.
  4. Waistband Design: The waistband plays a crucial role in the overall fit. Our run shorts feature a wide, elastic waistband that sits comfortably on your hips without digging in. Some of our shorts also include adjustable drawstrings which are also beneficial for achieving a customized fit.
  5. Pockets and Storage: Consider your storage needs. Some runners prefer shorts with pockets to carry essentials like keys, cards, or energy gels. All of our TCA running shorts feature strategically placed pockets that are easily accessible without causing discomfort.
  6. Reflective Elements: If you're running in low-light conditions, reflective details on your shorts enhance visibility and safety. If you plan to run during early mornings, evenings, or in areas with limited lighting, our Flyweight run shorts with reflective elements are the perfect choice!

Tailored Comfort

Before anything else, running shorts need to be comfortable and align to even your most powerful strides. No matter if you’re enjoying a light run or performing sprints after a weightlifting session, shorts must conform to your needs.

That’s why our shorts are lightweight and breathable, while also offering essential functions like enough zippable pocket space for smartphones. Moreover, our shorts are designed with materials such as QuickDry fabric, which allows you to remain hygienic and feel comfortable during the hardest workouts.

Our elastic waistbands and adjustable fit means our shorts can conform to any body type. We also include many sizes, from XS to XXL and beyond, ensuring you always find the fit you need. This way, if you’re unsure about your fit, you can always order the size up and close the waist gap to fit you.

Luckily, as many of our shorts are adjustable and comfortable to wear, it’s easy for a slightly larger fit to work well for many people, so if in doubt, consider choosing a size up and make use of the adjustable strap.

With ladies running shorts, a slightly looser fit that remains secure at the waist can be very comfortable and help with breathability.
