Keyboard Sleeve Sizing Guide: Flow, Flow Lite, and Flow 2 Fit

Quick answer

For Lofree Flow or Flow Lite, choose the Keyboard Sleeve for Flow/Flow Lite (351mm x 155mm). For Flow 2, choose the Keyboard Sleeve for Flow 2 in the size that matches your layout: 68-key, 84-key, or 100-key. Both are PU leather sleeves, but they are not interchangeable because the Flow 2 sleeve is sized specifically for that keyboard family.

Why sleeve sizing is not one-size-fits-all

A sleeve that is too loose lets your keyboard slide around inside a bag, which can lead to scratches or dents. A sleeve that is too tight puts pressure on keycaps and the case, and it can be difficult to insert or remove. Lofree makes two distinct sleeves because the Flow/Flow Lite family and the Flow 2 family have different dimensions and layout options.

The Keyboard Sleeve for Flow/Flow Lite measures 351mm x 155mm and is designed for models such as the Flow100 and Flow Lite100. The Keyboard Sleeve for Flow 2 also measures 351mm x 155mm but comes in multiple sizes to fit 68-key, 84-key, and 100-key layouts. The shared footprint does not mean they are interchangeable; the internal sizing and cutouts are tailored to each keyboard family.

Measure your keyboard before you buy

You only need a ruler or tape measure. Measure the width, depth, and height of your keyboard, including keycaps if they sit above the case. Compare those numbers to the sleeve dimensions. If your keyboard is within a few millimeters of the sleeve size, it should fit, but always check the layout compatibility listed for the sleeve.

For Flow 2, the sleeve is available in 68-key, 84-key, and 100-key sizes. If you own a Flow 2 100, choose the 100-key sleeve. If you own a Flow 2 84, choose the 84-key sleeve. The same logic applies to the Flow/Flow Lite sleeve: it is sized for Flow100 and Flow Lite100, so if you have a different layout in that family, it may not fit as intended.

Material and protection: what PU leather gives you

Both sleeves are made from PU leather, which is a durable synthetic material that resists scratches and dust. It is not a hard case, so it will not protect against heavy crushing or drops. Think of it as a soft shield for travel and storage, not a replacement for a padded bag or hard case.

The Keyboard Sleeve for Flow 2 weighs 210g, which is light enough to carry daily without adding noticeable bulk. The Keyboard Sleeve for Flow/Flow Lite does not list a weight, but it uses the same PU leather construction and measures 351mm x 155mm. If you need maximum impact protection, pair the sleeve with a padded backpack compartment.

Layout matters more than brand for 65 percent and 84 key keyboards

If you are searching for a 65 percent keyboard sleeve or an 84 key keyboard case, the key is not the brand name but the actual dimensions and layout of your keyboard. A 65 percent keyboard is usually more compact than a 75 percent or TKL board, so a sleeve designed for a larger layout may be too loose. Always match the sleeve to the keyboard's layout size, not just the brand.

Lofree's Flow 2 sleeve comes in 68-key and 84-key options, which cover many compact layouts. The Flow/Flow Lite sleeve is sized for 100-key models, so it is better suited to full-size or 100-key compact boards. If you have a 65 percent keyboard from another brand, measure it and compare to the sleeve dimensions before ordering.

Decision rules for choosing your sleeve

• If you own a Flow 2 100: Choose the Keyboard Sleeve for Flow 2 in the 100-key size. It is sized for the Flow 2 family and will fit the 100-key layout without excess room. Check your layout number before adding to cart.
• If you own a Flow 2 68 or 84: Choose the Keyboard Sleeve for Flow 2 in the 68-key or 84-key size respectively. The sleeve is available in these sizes to give a snug fit. A snug fit reduces movement inside the sleeve.
• If you own a Flow100 or Flow Lite100: Choose the Keyboard Sleeve for Flow/Flow Lite. It measures 351mm x 155mm and is designed for these models. Do not use the Flow 2 sleeve for a Flow or Flow Lite keyboard.
• If you need maximum drop protection: PU leather sleeves protect against scratches and dust, not hard impacts. For heavy travel, combine the sleeve with a padded bag or hard case. Match the protection level to your travel conditions.

Product facts

• Keyboard Sleeve for Flow/Flow Lite: Measures 351mm x 155mm and is compatible with LOFREE Flow100 and Flow Lite100 keyboards. This is the correct sleeve for Flow or Flow Lite owners who have a 100-key layout. If you have a different layout in that family, check the dimensions carefully.
• Keyboard Sleeve for Flow 2: Available in sizes to fit 68-key, 84-key, and 100-key layouts, with dimensions of 351mm x 155mm and a weight of 210g. Flow 2 owners must choose the size that matches their exact layout. The 210g weight keeps travel light, and the PU leather resists scratches and dust.

If you own this keyboard, the Flow 2 sleeve in 100-key size is the intended match. The low-profile design means the sleeve does not need extra height.
