Is it better to size up or down on jeans?

Deciding whether to size up or down on jeans can be tricky, as it depends on the denim’s material, your body shape, and how you prefer your jeans to fit. Generally, if jeans are made of 100% cotton, sizing up is often recommended because they will shrink. For stretch denim, sizing down might be better as they can loosen considerably with wear.

Sizing Jeans: To Size Up or Down?

The age-old question of whether to size up or down on jeans is a common one. Many factors influence this decision, from the fabric composition to personal preference. Understanding the characteristics of different denim types is key to achieving the perfect fit.

The Impact of Denim Material on Sizing

Denim isn’t just denim; its composition significantly affects how it behaves over time and with washing. This is the most crucial factor to consider when deciding on your jeans size.

100% Cotton Denim: The Shrink Factor

Jeans made from 100% cotton are known for their classic feel and durability. However, they also have a tendency to shrink, especially in the wash and dry cycle. If you’re purchasing rigid, non-stretch denim, it’s often advisable to size up.

This allows for the initial shrinkage that will occur. Over time, these jeans will mold to your body, offering a comfortable and personalized fit. Trying them on after a wash can give you a better idea of their final dimensions.

Stretch Denim: The Loosening Effect

Modern jeans frequently incorporate elastane (spandex or Lycra) to provide stretch and comfort. While this makes jeans more forgiving initially, it also means they can bag out or loosen considerably with wear. For stretch denim jeans, it’s generally recommended to size down.

The idea is that they will stretch to fit you comfortably after a few wears. If you buy them in your usual size, they might become too loose and saggy. This is particularly true for skinny jeans or jeggings.

How to Determine the Right Size for You

Beyond the fabric, several other considerations can help you make the right sizing choice for your new jeans. Trying them on correctly is paramount.

Trying On Jeans: Key Fit Points

When trying on jeans, pay close attention to a few critical areas. The waistband should feel snug but not digging in. You should be able to fit one or two fingers comfortably between the waistband and your body.

The seat and hips should also feel secure without being overly tight or restrictive. You should be able to move freely, bend, and sit without feeling like the jeans are pulling or constricting. The thighs should have a comfortable amount of room, whether you prefer a slim or relaxed fit.

The "Sit Test" and "Squat Test"

A crucial step in determining the right size is performing the "sit test" and the "squat test." Sit down on a chair or the edge of a counter. If the waistband digs uncomfortably into your stomach or if the back gapes significantly, the fit is likely off.

Next, perform a squat. This tests the flexibility and give of the denim, especially in the seat and thighs. If you feel excessive pulling or restriction, the jeans might be too small, or the cut might not suit your body shape.

Understanding Jean Cuts and Styles

The cut of the jeans also plays a role in how they fit and how you should size them. Different styles are designed to sit and fit in specific ways.

Skinny Jeans vs. Straight Leg Jeans

Skinny jeans are designed to be form-fitting throughout the leg. For these, sizing down is often the best strategy, as they are meant to hug your legs. However, be mindful that sizing down too much can make them uncomfortable to put on or wear.

Straight leg jeans offer a more relaxed fit through the leg. They typically have a consistent width from the knee down. For these, your regular size is often a good starting point, but consider the fabric’s stretch.

Bootcut and Flare Jeans

Bootcut jeans are fitted through the thigh and knee and then flare out slightly from the knee down. This style is quite forgiving. Your usual size is usually appropriate, as the flare is designed to accommodate footwear.

Flare jeans have a more pronounced flare than bootcut styles. Like bootcut jeans, they are generally sized according to your regular fit, with the flare adding a stylistic element rather than impacting overall fit significantly.

When to Consider Sizing Up

There are specific scenarios where sizing up is the more prudent choice. This often relates to the fabric and your desired comfort level.

• Rigid Denim: As mentioned, 100% cotton or other rigid denim will shrink. Sizing up ensures they will eventually fit well after washing.
• Pre-Shrunk or Washed Denim: Some jeans are pre-shrunk. Always check the label. If they are already washed, they may have undergone most of their shrinking.
• Layering: If you plan to wear thick socks or thermal layers under your jeans, sizing up can provide necessary room.
• Comfort Over Style: If maximum comfort is your priority and you don’t mind a slightly looser fit, sizing up can be a good option.

When to Consider Sizing Down

Conversely, sizing down is often the better approach for jeans with a significant amount of stretch.

• High Stretch Content: Jeans with 2% or more elastane will stretch out. Sizing down allows them to conform to your body.
• Skinny or Super Skinny Fits: These styles are meant to be tight. Sizing down ensures they maintain their intended silhouette.
• Preference for a Snug Fit: If you prefer your jeans to feel very fitted and supportive, even if they need a little stretching initially.
• Brands Known to Stretch Out: Some brands are notorious for their denim loosening up. Research reviews for specific brands.
