Lightest Ultrabook laptops
Lightest Ultrabook laptops, $840–$1400, 5 models.
Recommended models
Ultrabooks are bought by the gram. We ranked the class by weight, lightest first, and the top five tells a clean story: Samsung's Galaxy Book line owns the sub-kilogram bracket, HP's EliteBook Dragonfly matches it at a firm price, and the newest ASUS and MSI entries weigh slightly more while carrying 2025–2026 hardware. Note that most prices in this tier are formula estimates rather than firm listings — we mark them with ≈.
The weight champion: Samsung Galaxy Book (0.87 kg)
The lightest machine in the class weighs 0.87 kg — about 40% below the ultrabook median of 1.46 kg. The 2022 Samsung Galaxy Book pairs that with a Core i5-1240P, a mainstream-tier chip that holds its own for office and everyday work. The trade-off the data makes explicit: performance sits about 34% below the class median. That is the physics of the segment — you spend the watts on portability, not peak speed. Current value estimates put it around $840 ≈.
The firm-price alternative: EliteBook Dragonfly G4
Close behind, the HP EliteBook Dragonfly G4 (2023) is the lightest machine in the class with a firm listing price: $846. For buyers who want sub-kilogram portability without estimate uncertainty, it is the pick of the table. The remaining two rows are the 2025 ASUS ($1,232 ≈) and the 2026 MSI ($1,400 ≈) — newer and faster, but at roughly 50–70% more money for machines that still prioritize thin-and-light over performance.
What to check before you buy
- Weight and performance trade off directly here. Every sub-kilogram machine in the top five scores below the class performance median — decide which axis you are actually buying.
- Mind the ≈ marks. Three of the five prices are estimates; treat them as ballparks and verify the listing.
- Newer is pricier, not lighter. The 2025–2026 entries did not beat 0.87 kg — they bought performance with the same weight budget.
Bottom line
The lightest used ultrabook in the catalog is the 0.87 kg Samsung Galaxy Book at roughly $840 ≈, with the HP Dragonfly G4 at a firm $846 as the no-estimate alternative.
