Logitech K740 vs K800: Differences & Similarities


The Logitech K740 Illuminated Keyboard is one of the stylest keyboards that you can get your hands on. It’s quite steady and the surface grip is flawless as well.

The K740 is 45cm long (17’’), nearly 20cm (7.8’’) at the widest and about 3cm (1.4’’) thin. The K740 is one of the thinnest keyboards available in the market.

The Logitech K740 weighs around 1.3kg (46.7oz) and it’s quite heavy but it’s a wired one so weight really doesn’t count here.

On the other hand, the Logitech K800 is slightly thicker than K740 because it’s a wireless keyboard and needs additional space for batteries.

The Logitech K800 is somewhere about 46cm (18’’) long, nearly 20cm (7.8’’) at the widest and 5.8cm(2.2’’) thick. The Logitech K800 weighs around 750g (26.4oz) without batteries and somewhere around 1kg with batteries.


The Logitech K740 is a wired ultra-slim keyboard and it comes with a 6ft long USB cable. Logitech isn’t really famous for its keyboards but K740 is really exceptional from them.

Moving on, the Logitech K800 is a completely wireless keyboard and it is also equipped with ‘Advanced Logitech 2.4Ghz Sensor’ which means that you can use the keyboard while sitting a long way from your computer.


Both of these Logitech devices are more than a decade old but they’re still ruling the market and people are still using them.

The Logitech K740 and Logitech K800 Illuminated are still worth quite a lot and it’s not cheap to get your hands on these keyboards.

The Logitech K800 Illuminated Keyboard is just slightly more expensive than K740. The Logitech K800 and Logitech K740 are readily available on Amazon and you can find some good deals on them as well.

Durability and Comfort

There’s really no question in the durability and comfort of these keyboards. The keys are well placed and the palm rest with soft rubber coating is really comfy as well.

Both of these keyboards are pretty looking and provide a pleasant typing experience. As for the durability, the keys won’t come off easily and these keyboards will last much longer than any standard keyboard.

If you’re used to working on Lenovo’s ThinkPad laptops then these illuminated keyboards are the best thing that can happen to you.


The Logitech K740 and Logitech K800 are considerably different from each other in their designs but both of them look really beautiful and professional.

The K740 has a minimalist matte-black design with a nice palm rest at the bottom and a Logitech logo at the bottom as well.

All the keys are well-placed and it’s ideal for people who spend most of their time typing. 

The Logitech K800 looks a little more refreshing than K740 but has the same minimal matte-black design concept.

The orange marking on the keys and the clean outlines are also a nice touch with the palm rest and Logitech logo at the bottom of the keyboard.

I feel that K800 is more beautiful than K740 because it’s a tad more futuristic.


With these Logitech K740 and Logitech K800 keyboards, you’ll get laser-etched backlight keys that ensure that you can easily type in the dark.

Another perk of these keyboards is that they are featured with Logitech PERFECTSTROKE Key System which means that you’ll make no noise while typing.

Logitech K740 and Logitech K800 are without any doubt, one of the best low-profile silent keyboards that you can get your hands on. The Keycaps are quite impressive and perform pretty well.

Logitech K740 Illuminated Keyboard Review

The Logitech K740 Illuminated Keyboard is one of the best low-profile keyboards ever made.

Pleasant and comfortable typing, elegant design and the backlit keys are a sight for sore eyes.

The K740 is a complete package. The thing that I liked the most about this keyboard is its backlit keys.

Being a writer, it’s really important to some lights on to write at night but these backlit keys are the deal-breaker here.

The silent feature of this keyboard is another thing that I’d like to appreciate in this keyboard.

Most of the Logitech devices are specifically made for gaming but we cannot say the same thing for K740.

Because it’s better suited for office or home use and gaming with this keyboard won’t be that good.

Overall, the Logitech K740 is an exceptional keyboard and I’d definitely recommend this keyboard if you’re looking for a new one.
