The best thin laptop of 2026 is the MacBook Air 13 with the M5 chip, with the ASUS Zenbook S 14 as the top Windows alternative. Apple announced the M5 MacBook Air on March 3, 2026; it weighs 2.7 pounds and is about 0.44 inches thick at its tallest point.

| ASUS Zenbook S 14 | Best thin Windows laptop | 14-inch 3K OLED | About 2.7 lb | About 0.5 in | Upper |

Best overall: MacBook Air 13 (M5)
Multiple 2026 roundups rank it first overall. It has two Thunderbolt 4 ports, a thin body and a long battery life. It suits students, commuters and anyone who wants a quiet machine without a fan.
Trade-off: limited ports and non-upgradeable memory, so buy enough RAM at purchase.
Best thin Windows laptop: ASUS Zenbook S 14
Forbes names it the best lightweight laptop, citing a weight near 2.7 pounds and a 3K OLED display. The configuration in that review used an Intel Core Ultra 9 with 32 GB of RAM and 1 TB of storage. It is about half an inch thick.
Trade-off: premium pricing for top configurations.
Best for Windows on Arm: Microsoft Surface Laptop
Technobezz picks the 13.8-inch Surface Laptop for Windows users, pairing a Snapdragon X2 Elite with 16 GB of RAM. Caveats include Windows-on-Arm app compatibility and a modest 1920 by 1280, 60Hz display in some listings.
Best lightest: LG Gram 14
A 14-inch Gram with an AMD Ryzen AI 7 450 at around 2.5 pounds, 16 GB of RAM and a 1 TB SSD is listed as a lightest pick in one roundup. LG Grams trade rigidity for weight, so the chassis flexes more than a MacBook.
Best large-screen thin: LG Gram Pro 17
For anyone who wants a 17-inch screen without the typical weight, the Gram Pro 17 comes in at about 3.84 pounds according to one roundup.
Best thin business laptop: ThinkPad X1 Carbon
A roundup lists the latest X1 Carbon at around 2.17 pounds, making it among the lightest business-class laptops. The keyboard and port selection are better than most ultrabooks.
How thin is thin? A quick scale
| Class | Weight | Thickness | Typical trade-off |
|---|---|---|---|
| Ultralight | Under 2.5 lb | Under 0.6 in | Flexier chassis, fewer ports |
| Thin and light | 2.5 to 3.2 lb | 0.4 to 0.6 in | Balanced; best for most buyers |
| Thin performance | 3.2 to 4 lb | 0.6 to 0.7 in | More power, shorter battery on heavy tasks |
Weight carried per year: a worked example
If you carry a laptop 250 days a year and your commute adds up to 2 hours with the bag, then a laptop that is 1 pound lighter saves 250 pounds of carried load over the year. The difference is small per trip but adds up for daily commuters.
What to check before buying
- Memory: thin laptops often have soldered RAM. Buy at least 16 GB.
- Ports: check for USB-C, HDMI and headphone jacks. Some slim models only have two USB-C ports.
- Cooling: thin chassis limit sustained performance, so heavy tasks may throttle.
- Display: OLED looks better but uses more power; IPS may last longer on battery.
- Battery: thinner bodies hold smaller batteries, so check expected runtime.
- Repairability: thin laptops often have glued or soldered parts, which shortens lifespan.
Decision matrix: which thin laptop for which person?
| Your situation | Choose | Why |
|---|---|---|
| Apple user, long battery, quiet | MacBook Air 13 M5 | Fanless, thin, long battery life |
| Windows, OLED, premium feel | Zenbook S 14 | 3K OLED at about half an inch |
| Wants the least weight | LG Gram 14 | About 2.5 lb |
| Business traveler, strong keyboard | ThinkPad X1 Carbon | Light and rugged enough for travel |
| Wants a big screen without bulk | LG Gram Pro 17 | 17 inches near 3.8 lb |
Ownership realities of thin laptops
Thin machines trade serviceability for size. Memory is usually soldered, and storage may be soldered on some models, so the configuration you buy is the one you keep. Batteries are often glued in, which makes replacement slower and pricier once capacity fades, typically after several years of daily cycles. To extend life, avoid charging to 100 percent every day if the software offers an 80 percent limit, keep vents clear, and use a hard-sided or padded sleeve in a crowded bag. Light chassis dent more easily than thicker ones, so avoid putting heavy items on top of your laptop in a backpack.
Ports deserve attention too. Two USB-C ports mean a dock or hub for external monitors and a mouse. Choose a hub with power pass-through, so you can charge while using it, and check that your laptop’s ports support the display output you need.
