JanSport Size Guide
JanSport is a reliable brand specialising in backpacks and bags designed for students and travellers. Known for durability and practical design, JanSport sizing tends to follow standard UK sizing conventions. However, the brand's primary focus is on backpacks and travel gear, where capacity and fit recommendations are based on intended use rather than traditional clothing measurements. When purchasing JanSport clothing items, always check the product-specific size chart, as fit can vary depending on the item type (slim fit, regular fit, etc.). We recommend reading customer reviews for real-world fit feedback before making a purchase.
How to Measure
- For Backpack Capacity: Consider your intended use and trip duration. Small backpacks (25–30 litres) suit school and short trips, whilst medium packs (30–45 litres) accommodate longer days and travel.
- For Clothing – Chest: Wear a well-fitting shirt. Measure around the fullest part of your chest with the tape measure held snugly (not tight) under your arms. Keep the tape parallel to the ground.
- For Clothing – Waist: Measure around your natural waist (the narrowest point) with the tape held comfortably, allowing one finger to fit between the tape and your body.
- For Clothing – Length: For tops and jackets, measure from the top of your shoulder (at the base of your neck) straight down to your desired hem length. For trousers, measure from your hip down the inside seam to your ankle.
- Timing: Measure yourself in the evening, as feet and body can swell during the day. This ensures a more accurate fit.
- Use a Flat Surface: Stand on a hard, flat surface without shoes when measuring for the most precise results.

Product-Specific Guidance
Backpacks & Bags: JanSport backpacks are designed for durability and functionality. Choose your backpack size based on your specific needs and expected duration of use. Small packs are ideal for daily school use and weekend trips, whilst medium capacity packs suit longer travel and multi-day excursions. Check the product description for detailed pocket layouts, material composition, and weight capacity to ensure the pack meets your requirements.
Casual Clothing: JanSport's clothing line emphasises comfort and practicality. Sizing follows standard UK conventions, but fit can vary by item type. Tops and hoodies may be available in slim or regular fit versions – review the product-specific size chart before ordering. Layering pieces like jackets should be tried over the clothing you plan to wear underneath.
Accessories: Smaller items such as pencil cases, water bottles, and pouches are typically one-size-fits-most. Check individual product dimensions to ensure compatibility with your backpack or bag.
Sizing Tips
- Check Product-Specific Charts: Always refer to the individual product size chart before making a purchase, as fit can vary between different JanSport items and collections.
- Read Customer Reviews: Customer feedback often reveals how a particular item fits in reality. Pay attention to comments about sizing running large, small, or true to size.
- Consider Item Type: Slim-fit items will feel tighter than regular-fit equivalents in the same size. Adjust your choice accordingly.
- Account for Layering: If you plan to wear a JanSport jacket or hoodie over multiple layers, size up to ensure comfortable movement and a proper fit.
- Backpack Try-On: If purchasing a backpack online, pay careful attention to capacity ratings and customer photos showing the pack in use. Capacity in litres is more reliable than vague size descriptors.
- Contact Customer Service: JanSport's customer service team can provide detailed fit advice. Do not hesitate to reach out if you are between sizes or unsure about a specific product.
- Measure Both Feet: One foot is often slightly larger than the other. If purchasing any footwear, ensure the size accommodates your larger foot.
- Leave Room for Growth: If buying for a young student, consider leaving a small amount of growing room, particularly in backpack capacity, so the pack remains useful as they grow.
