How To Choose The Best Backpacks For 8th Graders
An 8th grader’s backpack has to handle a lot — heavy textbooks, a laptop, gym clothes, a lunch bag, and a water bottle. Picking the right one means thinking about capacity, laptop protection, comfort, and build quality in a way that matches a middle schooler’s actual day.
Capacity and Size
Look for a bag with a volume in the 20 to 34 liter range. Too small, and binders and sports gear won’t fit. Too large, and the bag gets heavy and awkward for a smaller frame. The best size sits between 20L and 26L for most 8th graders, though bigger teens may prefer a 34L option for extra gear.
Laptop Sleeve
Most schools now issue Chromebooks or ask for personal laptops. Check the sleeve size — 15 inches is common, but 15.6-inch and 16-inch sleeves exist too. A padded sleeve keeps the device safe in a crowded bag.
Water Bottle Pockets
Middle schoolers need to stay hydrated. Side pockets that fit a standard 32-ounce bottle are useful. Some bags now accommodate a 40-ounce tumbler, which is great for long school days.

In‑Depth Reviews
1. LOVEVOOK School Backpack for Teen Girls
$29.99$49.99as of Jul 5, 12:03 AMThe 14-pocket organizer that keeps 8th graders ready and their parents impressed.
This bag stands out because it solves the biggest daily pain: finding stuff fast. With 14 smart pockets, it neatly holds textbooks, binders, a 15.6-inch laptop, and a free pencil case. The giant side pockets handle up to a 40-ounce tumbler, so hydration is never an issue. Buyers report it is the “right size for iPad and extras” and call out the smart compartments, water-resistant build, and lightweight feel at just 1.8 lbs — making it a great fit for middle schoolers.
Unlike the BIKROD backpack below, which offers fewer pockets and a more basic build, the LOVEVOOK comes with a removable Velcro logo and reflective strips on the shoulder straps for visibility during early mornings. The breathable airflow back panel and padded shoulder straps keep it comfortable even when fully loaded. One reviewer noted their daughter carries “a ton of stuff” and the bag holds up well, confirming its daily durability.
Why it stands out
- 14 pockets keep everything organized without digging
- Fits a 40-ounce water bottle in the side pocket
- Water-resistant nylon fabric shrugs off spills and light rain
- Removable Velcro logo lets kids personalize with patches
What to watch for
- Some reviewers wish for more color variety beyond khaki
- The 1.8 lb weight is light, but not the lightest option available
Best for: 8th grade girls who want a cute, organized backpack that fits a laptop, water bottle, and all their gear without looking bulky.
Keep in mind: The khaki color may show dirt more than darker options, but the material is easy to clean according to buyers.
2. adidas Excel 7 School Backpack, 34L
$39.00as of Jul 5, 12:03 AMThe 34-liter workhorse built for the 8th grader who carries everything, everywhere.
The LoadSpring shoulder strap technology helps ease the weight, so your student feels less strain during long walks between classes. Owners mention it is “very spacious” and one parent bought it “for three years straight because my daughter loved it” — a strong sign of repeat trust.
The dedicated padded laptop sleeve protects up to a 16-inch device, which is 3% larger capacity than the 15.6-inch sleeve in the BIKROD backpack. Two mesh side pockets each fit a 32-ounce water bottle. While this bag is not intended for children 12 and under, it works well for 8th graders (typically 13-14 years old). At just 1.37 pounds, it is lighter than the LOVEVOOK despite having nearly double the capacity.
What works
- 34L capacity fits textbooks, gym gear, and a laptop in one bag
- LoadSpring straps reduce shoulder strain on heavy days
- Lightweight at 1.37 lbs despite the size
- Durable materials with no wear after weeks of use per reviews
The trade-off
- May look bulky on smaller 8th graders
- Not recommended for kids 12 and under
Reach for this if: your teen carries a laptop, gym clothes, and heavy textbooks daily and needs a bag that distributes the weight comfortably.
Look elsewhere if: your child is small-framed or under 13, as the 34L size might be overwhelming.
3. Simple Modern Ellis Backpack, 20L
$64.99as of Jul 5, 12:03 AMThe 20-liter backpack that survives a whole school year without needing a replacement.
Simple Modern built the Ellis for longevity. Made from easy-to-clean, water-resistant Cordura polyester, this bag handles spills and daily abuse without fraying. One buyer wrote that their son “carried this backpack all year long” and it “held up perfectly” — unusual praise for a kid who usually needs a new bag every semester. The reinforced stitching and padded adjustable shoulder straps add to the durability.
At 20 liters, the Ellis is smaller than the adidas Excel 7 (34L) and the Under Armour Hustle Sport (26L), but that size is intentional: it fits an 8th grader’s frame without looking oversized. The padded laptop sleeve fits up to a 16-inch device, matching the adidas in laptop capacity. Two expandable bottle sleeves hold water bottles, and the luggage sleeve is handy for travel. The Hopscotch Checkmate pattern adds a stylish touch that both boys and girls appreciate.
Why it wins
- Cordura polyester fabric is water-resistant and easy to clean
- Survives a full school year per multiple verified reviews
- Fits a 16-inch laptop in a padded sleeve
- Padded shoulder straps with reinforced stitching add strength
Consider this
- 20L capacity is smaller than the adidas (34L) and Under Armour (26L)
- Limited pocket count compared to the LOVEVOOK’s 14 pockets
Perfect for: families who want one backpack to last multiple semesters without fraying or breaking.
Not ideal if: your 8th grader needs maximum capacity for sports gear and heavy textbooks daily.
4. JanSport Big Backpack – Bad Bows
$54.99$62.00as of Jul 5, 12:03 AMThe extra-large JanSport that swallows binders, books, lunch, and still has room.
JanSport is a trusted name for school backpacks, and the Big Backpack lives up to the reputation. With two large main compartments and a dedicated 15-inch padded laptop sleeve, it handles a heavy high school load — which means it easily covers an 8th grader’s needs. Customers note it “fits many binders, books, and extras” and holds up to daily use without wearing out. At just 16 ounces, it is one of the lightest options despite its high volume.
Unlike the LOVEVOOK, which has 14 pockets, the JanSport focuses on two huge compartments and several utility pockets, making it simpler to organize. The ergonomic S-curve shoulder straps and fully padded back panel provide comfort for long days. One teacher even uses it as their daily bag, praising the adjustable straps and multiple pockets. The Bad Bows pattern is a standout design that adds personality.
What we like
- Extra-large capacity fits 3-inch binders and lunch easily
- Weighs only 16 oz, making it light even when fully loaded
- Machine washable for easy cleaning
- Ergonomic S-curve straps reduce shoulder strain
What to know
- Some reviewers wish for more boy-friendly designs
- 15-inch laptop sleeve may not fit larger 16-inch devices
Best for: 8th graders who carry a lot of books and binders and need a light, durable backpack that simplifies organization.
Skip if: you need a dedicated 16-inch laptop sleeve, as this bag maxes out at 15 inches.
5. Under Armour Hustle Sport 6.0 Backpack
$27.00$50.00as of Jul 5, 12:03 AMThe water-resistant workhorse that stays looking new after weeks of daily use.
Under Armour’s UA Storm technology makes this backpack water-resistant, keeping school essentials dry during unexpected rain. With a 26-liter capacity, it is smaller than the adidas Excel 7 (34L) but still roomy enough for a 16-inch laptop, lunch box, folders, and a water bottle. Buyers love that the “high-quality zipper looks new after weeks” and the bag fits “lunch box, folder, water bottle, and jacket” — exactly the daily carry an 8th grader needs.
While the BIKROD backpack below has a larger 18-inch height, the Under Armour measures 20 inches deep and wide, giving it a boxier shape that holds more bulk. The abrasion-resistant coated bottom adds durability where bags typically wear out first. The bungee-adjust front closure is great for stashing a jacket or soccer ball after practice. One parent called it “very durable for my 6-year-old,” showing it scales down nicely for smaller kids too.
Standout features
- UA Storm water-resistant coating keeps contents dry
- Abrasion-resistant coated bottom for long-term durability
- Deep side pockets fit a 32-ounce water bottle
- Bungee front closure holds jacket or ball securely
One downside
- At 26L, it offers less capacity than the adidas Excel 7 (34L)
- Dimensions are 20 inches cubed, which may be wider than some lockers
Grab this for: an 8th grader who walks to school in all weather and needs a durable, water-resistant bag that won’t wear out.
Be aware: the boxy 20-inch shape may not fit slim lockers as easily as narrower bags.
6. BIKROD School Backpack with USB Charging Port
$26.99as of Jul 5, 12:03 AMThe entry-level bag with a USB port that works best for light loads.
At an entry-level price, the BIKROD backpack offers a surprising feature set: a USB charging port, a separate padded compartment for a 15.6-inch laptop, and an anti-theft hidden back pocket. The main compartment has room for an iPad, mouse, charger, binders, and clothes. Mesh side pockets hold water bottles and umbrellas. However, one buyer mentioned a “broken buckle after two months of use” — the plastic buckle snapped during daily school use, leading the seller to offer a partial refund or replacement.
Compared to the LOVEVOOK, which has 14 pockets and a 7-inch depth, the BIKROD has just 4 pockets and measures 8 inches deep by 12 inches wide by 18 inches tall — a 2.5x smaller capacity than the Under Armour’s 20-inch dimensions. The padded straps are comfortable, and the bag works well for a lighter load. One owner reported the “excellent padded laptop slot” lasted three years of college use, but the water bottle pockets degraded over time. It is suitable for ages 3 and up, making it a versatile choice for younger siblings too.
Budget bonuses
- Built-in USB charging port lets you charge devices on the go
- Padded laptop compartment fits up to 15.6-inch devices
- Anti-theft hidden back pocket for valuables
- Lightweight and easy to carry for a 14-year-old per reviews
Watch out for
- Plastic buckle reported to snap within two months by one buyer
- Only 4 pockets — less organization than the LOVEVOOK’s 14
- Water bottle pockets may degrade over time per long-term reviews
Good pick if: you need a budget-friendly backpack with USB charging and a laptop sleeve for occasional use.
skip it if: your 8th grader is hard on bags — the plastic buckle may not survive a full semester of daily use.
Understanding the Specs
Capacity and Volume
Capacity is measured in liters (L) and tells you how much the bag can hold. For an 8th grader, 20 to 26 liters is a great everyday size — enough for textbooks, a laptop, lunch, and a water bottle. A 34-liter bag like the adidas Excel 7 offers extra room for gym clothes or sports gear, but may be too large for smaller frames.
Laptop Sleeve Size
The laptop sleeve size tells you what size device fits safely. A 15-inch sleeve fits most standard school laptops, while a 15.6-inch or 16-inch sleeve accommodates larger devices. Always check this spec — putting a 16-inch laptop into a 15-inch sleeve can damage the device or stretch the fabric over time.
