BookArc vs. BookArc Flex: Which Vertical MacBook Stand Fits Your Setup?

Quick answer

The BookArc and BookArc Flex both hold your MacBook vertically to free up desk space, but they differ in how they fit your laptop. The original BookArc uses swappable inserts to match specific MacBook models, while the BookArc Flex has a flexible design that adjusts to fit a range of sizes. If you already own a BookArc and need to support a newer MacBook, a replacement insert like Insert H or Insert E is the simplest fix. For a one-stand-fits-many solution, the Flex is more forgiving.

If you're shopping for a vertical MacBook stand, the Twelve South BookArc and BookArc Flex are two of the most recognizable options. Both lift your laptop off the desk and hold it on its side, but they approach fit and adjustability differently. The original BookArc relies on model-specific inserts, while the Flex uses a more adaptable design.

This comparison breaks down the key differences using the supplied catalog facts, so you can decide which stand matches your MacBook and your workflow. We'll also cover how replacement inserts like Insert H and Insert E keep older BookArc stands compatible with newer machines.

How the two stands differ in design and fit

The original BookArc is a curved, arc-shaped stand that holds your MacBook vertically. It ships with an insert that cradles the laptop at the right angle. Because MacBook dimensions change between models, Twelve South offers different inserts to match specific sizes. The BookArc Flex, by contrast, uses a flexible, adjustable design that conforms to a wider range of MacBook sizes without swapping parts.

This difference matters if you upgrade your MacBook often or share a stand between laptops. With the original BookArc, you may need a new insert when you change models. With the Flex, you likely won't. However, the original BookArc's insert system can provide a more precise, secure fit for the exact model it's designed for.

• Check your MacBook model and year before buying an insert for the original BookArc.
• If you own multiple MacBooks of different sizes, the Flex may be more convenient.

Insert compatibility for the original BookArc

Twelve South sells replacement inserts that add compatibility for newer devices to the current BookArc (2015 and later). For example, Insert H adds support for the 14-inch MacBook Pro (M2, 2023), 13-inch MacBook Pro (M2, 2022), 14-inch MacBook Pro (M1, 2021), and 13-inch MacBook Pro (2020). Insert E adds support for the MacBook Air with Retina Display (2018-2019 models) and 13-inch MacBook Pro (2020).

Note that these inserts are not compatible with BookArc mod, BookArc for MacBook Air (pre-2015), or the previous version of BookArc for MacBook (pre-2015). If you're unsure which BookArc you have, check the insert numbering: previous versions came with numbered inserts (1-8), while the current model uses lettered inserts. This helps you confirm you're buying the right part.

• Insert H and Insert E are available in multiple colors to match your stand.
• Always verify your BookArc version before ordering an insert.

Adjustability and everyday use

The BookArc Flex is designed to adjust to different MacBook sizes, so you can switch between laptops without changing inserts. It's a good choice if you want a single stand that works with whatever MacBook you're using now or might use later. The original BookArc, with the correct insert, holds your MacBook at a fixed, stable angle that's tailored to that model.

Both stands save desk space by storing your MacBook vertically, which is ideal for closed-display mode with an external monitor. The Flex's flexibility may appeal to frequent travelers or those who often change devices, while the original BookArc's insert-based fit can feel more custom.

• Consider how often you change MacBooks: frequent switchers may prefer the Flex.
• If you use a single MacBook, the original BookArc with the right insert is a precise fit.

Trade-offs to weigh

• Fit precision vs. flexibility: The original BookArc uses model-specific inserts for a tailored fit, while the BookArc Flex adjusts to fit a range of MacBook sizes without extra parts. Choose based on whether you prioritize a custom fit or the ability to switch laptops easily.
• Upgrade path vs. future-proofing: If you already own a current BookArc, a $5 insert like Insert H or Insert E can extend its life with a newer MacBook. The Flex may avoid future insert purchases if you upgrade often. For a single MacBook that matches an available insert, the original BookArc is cost-effective. For frequent upgrades, the Flex may save hassle.
• Desk footprint and stability: Both stands hold your MacBook vertically to save space. The original BookArc's insert cradles the laptop at a fixed angle, while the Flex's adjustable design may suit different thicknesses. Consider the size of your desk and whether you need to adjust the angle or fit.

Which should you choose?

Best for

• Owners of a current BookArc (2015 and later) who need to support a specific MacBook model with an insert like Insert H or Insert E.
• Users who prefer a precise, model-specific fit and don't plan to change laptops often.

Not for

• Those with a pre-2015 BookArc or BookArc mod, as the inserts are not compatible.
• People who frequently switch between different MacBook sizes and want a single stand that adapts without inserts.

The right choice comes down to your MacBook model and how often you change it. If you have a current BookArc and a compatible MacBook, a replacement insert is a simple, low-cost fix. If you want one stand that handles multiple sizes, the BookArc Flex is the more adaptable option. Either way, you'll free up desk space and keep your MacBook ready to use.
