Apr
Finding the perfect NBA jersey size can make all the difference between proudly showing off your team spirit and dealing with an uncomfortable fit that ends up collecting dust in your closet. Whether you’re shopping for an authentic game-worn style jersey, a versatile swingman, or a comfortable replica for casual wear, this comprehensive guide will walk you through everything you need to know about NBA jersey sizing.
Introduction to NBA Jersey Sizing
The right NBA jersey isn’t just about representing your favorite team or player—it’s about comfort, appearance, and even long-term value. A properly fitted jersey enhances your game-day experience, looks better in photos, and if you’re a collector, maintains better condition and potentially higher resale value.
NBA jerseys come in several different categories, each with distinct sizing characteristics:
- Authentic Jerseys: The exact jerseys worn by NBA players
- Swingman Jerseys: High-quality replicas with premium features
- Replica Jerseys: More affordable options designed for everyday fan wear
- Women’s Jerseys: Specifically cut and sized for women’s bodies
- Youth Jerseys: Proportioned for kids and teens
Understanding these differences is your first step toward finding your perfect fit. Throughout this guide, we’ll cover detailed size charts, measurement techniques, fit preferences, and insider tips to ensure you make the right choice when purchasing your next NBA jersey.
NBA Jersey Types and Their Fits
Before diving into specific measurements, it’s essential to understand how different jersey types are designed to fit.
Authentic Jerseys
Authentic jerseys are the pinnacle of NBA merchandise—identical to what the players wear on the court.
- Fit Profile: Engineered with an athletic, performance-oriented cut
- Characteristics: Slim through the body with slightly wider armholes for movement
- Sizing Note: Generally run slimmer than other jersey types, often requiring sizing up
- Materials: Lightweight, moisture-wicking fabrics with heat-pressed or stitched details
- Best For: Serious collectors and fans seeking the genuine NBA experience
Swingman Jerseys
The middle tier of NBA jerseys, swingman jerseys offer excellent quality at a more accessible price point.
- Fit Profile: More relaxed than authentics, but still sports-inspired
- Characteristics: Comfortable through chest and waist with a slightly longer length
- Sizing Note: Generally true to size for most wearers
- Materials: Durable polyester with high-quality embroidery and stitching
- Best For: Most fans seeking balance between authenticity and comfort
Replica Jerseys
Designed primarily for casual wear, replica jerseys prioritize comfort and affordability.
- Fit Profile: Relaxed, casual fit similar to a t-shirt
- Characteristics: Roomier throughout with standard armholes
- Sizing Note: Often run slightly large, consider sizing down for a fitted look
- Materials: Standard polyester with printed (rather than stitched) details
- Best For: Casual fans, everyday wear, or layering over other clothing
Understanding these fundamental differences will help guide your size selection process, especially if you’re choosing between different jersey types.
NBA Jersey Size Charts
Size charts are your most reliable tool for finding the right fit. While these measurements are generally consistent, always check the specific retailer’s size chart when available, as there can be slight variations between manufacturers and seasons.

Youth NBA Jersey Size Chart (Standard Measurements in Inches)
| Size | Chest Width | Body Length | Age Range (Approx.) |
|---|---|---|---|
| S (8) | 15-16 | 22 | 6-8 years |
| M (10-12) | 16-17 | 24 | 8-10 years |
| L (14-16) | 17-18 | 26 | 10-12 years |

Understanding these measurements is crucial—chest width is typically measured flat from armpit to armpit, while body length is measured from the top of the shoulder to the bottom hem. Sleeve opening measurements can be particularly important if you have larger arms or plan to layer underneath.
How to Measure Yourself for an NBA Jersey
Taking accurate measurements is the most reliable way to determine your ideal jersey size. Follow these steps for best results:
- Gather Your Tools
- Flexible measuring tape (cloth or plastic)
- Paper to record measurements
- A friend to help (recommended but not required)
- Measure Your Chest
- Stand with arms relaxed at your sides
- Wrap the measuring tape around the fullest part of your chest
- Keep the tape horizontal and snug (but not tight)
- Take a normal breath while measuring for accuracy
- Measure Your Waist (especially important for women’s jerseys)
- Find your natural waistline (typically at the narrowest part of your torso)
- Wrap the measuring tape around, keeping it parallel to the floor
- Measure after exhaling normally, not while holding your breath
- Measure Your Body Length
- Start at the highest point of your shoulder
- Run the tape down to where you want the jersey to end (typically mid-hip)
- For authentic fit, aim for about 2 inches below your waistband
- Consider Your Arm Size
- If you have larger arms, measure around the widest part of your bicep
- Compare to the sleeve opening measurement on the size chart
Pro Tips for Accurate Measurement:
- Wear the type of clothing you plan to wear under the jersey
- Don’t pull the measuring tape too tight
- Round up to the nearest half-inch
- Take each measurement twice to confirm accuracy
- Stand in a natural, relaxed posture
Avoid these common measurement mistakes:
- Measuring over bulky clothing
- Pulling the tape too tight
- Not keeping the tape parallel to the floor
- Measuring alone when assistance would provide better accuracy
- Forgetting to account for layering plans
Fit Preferences: Loose vs. Fitted, Layering, and Style
Your intended use and personal style preferences play a significant role in determining your ideal jersey size.
For a Loose, Casual Fit:
- Size up one size from your measurement-based recommendation
- Provides a relaxed, streetwear-inspired look
- Allows easy layering over hoodies or long-sleeve shirts
- More comfortable in hot weather or for extended wear
- Creates a traditional fan-in-the-stands appearance
For a Fitted, Athletic Fit:
- Choose your exact size based on measurements
- Creates a sleeker, more performance-oriented appearance
- Shows off your physique better
- More authentic to how players wear jerseys on court
- Less fabric to get in the way if you’re actually playing basketball
For Layering:
If you plan to wear your jersey over other clothing (especially in colder months), consider the following:
- For layering over t-shirts: Standard size should work
- For layering over hoodies or sweatshirts: Size up at least one size
- For substantial layering: Consider sizing up two sizes
Remember that authentic jerseys are already cut slimmer, so you may need to size up further if planning to layer with this jersey type.
Style Considerations by Jersey Type:
- Authentic: Already runs small; sizing up recommended for most wearers
- Swingman: True to size for standard fit; size up for loose fit, down for very fitted
- Replica: Often runs slightly large; consider your preferred fit carefully
The current trend among NBA players and style-conscious fans leans toward a slightly looser fit than in previous years, so keep this in mind if you’re aiming for a contemporary look.
Special Considerations for Women’s and Youth Jerseys
Women’s NBA Jerseys
Women’s jerseys feature a different cut than men’s versions, designed to better accommodate feminine body types:
- Narrower shoulders and chest
- More tapered waistline
- Slightly shorter overall length
- Different proportion of chest to waist measurements
When selecting a women’s jersey:
- Focus on both chest and waist measurements, not just chest
- Consider your height—taller women may prefer men’s sizes for length
- Note that women’s jerseys typically provide a more contoured fit
- Some women with broader shoulders or athletic builds may prefer men’s small or medium sizes
If you’re between sizes, consider your body type:
- More hourglass or pear-shaped? Size based on chest measurement
- More athletic or straight-figured? Consider sizing up for comfort
Youth NBA Jerseys
When purchasing for growing children, special considerations apply:
- Growth room is important—consider sizing up
- Age ranges on charts are approximations; measurements are more reliable
- Youth XL is often similar to an Adult XS or S
- Consider the child’s build—slimmer children may need smaller sizes despite age
- For teenagers close to adult sizes, adult small may offer better longevity
Parents should note that youth jerseys:
- Have proportionally shorter lengths
- Feature narrower shoulders
- May have slightly different designs than adult versions
- Are cut for less developed body types
For the best value, aim for a jersey that allows 1-2 years of growth while not appearing excessively oversized.
Brand and Model Variations
While we’ve provided general size guidelines, it’s important to recognize that sizing can vary between manufacturers and even between different lines from the same brand.
Nike (Current NBA Jersey Provider)
- Tends to run slightly slimmer in authentic jerseys
- Swingman jerseys are generally true to size
- Replica jerseys may run slightly large
Adidas (Previous NBA Jersey Provider)
- Generally ran more true to size across all jersey types
- Authentic jerseys were slightly looser than current Nike versions
- Women’s jerseys had less tapering at the waist
Mitchell & Ness (Retro and Throwback Jerseys)
- Authentic throwbacks often run very true to size
- Swingman versions generally run slightly large
- Special editions may have unique sizing notes
Fanatics (NBA Store Brand)
- Generally runs slightly larger than Nike equivalents
- More consistent sizing between jersey types
- Often preferred for those seeking a looser fit
When purchasing from different brands:
- Always check that specific brand’s size chart
- Read customer reviews for fit feedback
- Consider reaching out to customer service for assistance
- Be especially careful when ordering rare or collector’s editions
Common Sizing Mistakes and How to Avoid Them
Even experienced jersey buyers can make these common mistakes:
- Assuming your regular shirt size is your jersey size: Athletic gear often fits differently than casual clothing. Always check measurements.
- Ignoring the jersey type: Authentic, swingman, and replica jerseys all fit differently—factor this into your decision.
- Not accounting for layering plans: Failing to size up if you plan to wear a hoodie underneath can lead to an uncomfortable fit.
- Relying solely on alpha sizing (S/M/L) without checking measurements: Even within the same size, measurements can vary between brands and models.
- Not checking the return policy: Always verify you can exchange or return if the fit isn’t right.
- Applying men’s sizing expectations to women’s or youth jerseys: These have different proportions and cannot be directly compared.
- Buying based on how jerseys look on players: Remember that NBA players are typically much taller and more athletic than average fans.
- Prioritizing a bargain over proper fit: A discounted jersey that doesn’t fit well is never a good value.
To avoid these issues, always take fresh measurements before ordering, check specific brand size charts, and consider your wearing intentions before finalizing your selection.
NBA Jersey Sizing FAQs
Q: Should I size up if I plan to wear hoodies underneath my jersey? A: Yes. For lightweight hoodies, size up once; for thicker hoodies, consider sizing up twice, especially with authentic jerseys that already have a slimmer cut.
Q: What’s the difference between Swingman and Authentic jersey sizing? A: Authentic jerseys typically have a slimmer, more athletic cut designed for performance, while Swingman jerseys offer a more relaxed fit designed for comfortable fan wear. Authentics often require sizing up compared to Swingmans.
Q: How does NBA jersey sizing compare to NFL or NHL jerseys? A: NBA jerseys generally run slimmer than NFL jerseys (which are designed to fit over pads) and slightly more fitted than NHL jerseys. When switching between sports merchandise, check specific measurements rather than assuming consistent sizing.
Q: Which jersey type is best for collectors versus casual fans? A: Serious collectors typically prefer Authentic jerseys for their exact match to on-court styles, while casual fans often find better value and comfort in Swingman jerseys. Replicas are ideal for fans prioritizing comfort and affordability over exact authenticity.
Q: Can I tailor my NBA jersey for a better fit? A: Yes, but with caution. Side seams can be tailored by experienced sports garment specialists, but modifying jerseys, especially authentics or limited editions, may reduce collector value. Simple length hemming is the safest modification if necessary.
Q: Do NBA jerseys shrink after washing? A: Modern NBA jerseys are made from synthetic materials that resist significant shrinking. However, following care instructions (cold water, gentle cycle, air drying) will maintain the best fit over time.
Q: Is there a difference in sizing between home and away jerseys? A: No, the cut and sizing remain consistent between home, away, and alternate jerseys of the same type and brand.
Q: How should a jersey fit around the armholes? A: Armholes should allow comfortable movement without excessive gaping. Authentic jerseys have slightly wider armholes for athletic movement, while replicas have more standard sizing.
