Rocketbook Core Letter Size Review: A Reusable Notebook That Syncs to the Cloud
A full-page 8.5 x 11 notebook you write in with a real pen, scan with your phone, then wipe clean and use again.
The Letter-size Rocketbook Core gives you a full sheet of writing room and a genuinely simple scan-and-erase cycle, which makes it the stronger pick over the smaller Executive version for anyone who takes long meeting notes or full-page sketches.

The Rocketbook Core Letter Size is a reusable spiral notebook that lets you write by hand, scan the page into a cloud folder, then wipe the page and start over. It uses a grid layout with a redesigned, scratch-resistant cover and ships with the pen it's built around, a Pilot FriXion pen whose ink erases with friction and heat instead of a blade or solvent.
This review covers the Letter-size version specifically, at 8.5 x 11 inches, which is the larger of the two Rocketbook Core formats. Rocketbook also sells the same notebook in an Executive size at 6 x 8.8 inches, and later in this review we cover exactly who should pick which one. Every claim here comes from the product's own listing, not a spec sheet we're guessing at.
What the Rocketbook Core Letter Size Is, and Who It's For
The Rocketbook Core Letter Size is a spiral-bound notebook built to be written on, scanned, wiped clean, and reused, rather than filled once and shelved. Every page uses a grid layout, and the cover has been redesigned to resist scratches while you carry it in a bag or set it on a desk.
It fits people who take a lot of notes by hand but want those notes searchable and backed up later. A professional in back-to-back meetings, a student working through dense lecture notes, or anyone who sketches diagrams and wants them saved to a shared drive are all a good match. The Letter size in particular suits anyone who fills a page fast: long meeting minutes, wide diagrams, or multi-column planning grids all have more room to breathe than they would on a smaller pad.
- Best for: meeting notes, lecture notes, project planning grids, and full-page sketches or diagrams
- Also good for: anyone standardizing on one notebook that syncs straight to a team's existing cloud folders
- Skip it if: you need a notebook small enough for a jacket pocket — see the Executive-size note below

Book a ConsultationHow the Write, Scan, Erase Cycle Actually Works
Writing in the Rocketbook Core Letter Size works exactly like writing in a normal spiral notebook, because the included Pilot FriXion pen is a standard pen with heat-sensitive ink, not a special stylus. Once a page is full, the Rocketbook app reads the page and uploads it to the cloud destination you've set, including Google Drive, Dropbox, and Microsoft OneNote, among other services the app supports.
Grid pages carry printed Smart Titles and Smart Tags, small icons at the bottom of the page you check off before scanning. Checking a tag tells the app which cloud folder or naming pattern to route that page to, so a page marked for a client project lands in that project's folder automatically instead of a generic camera-roll dump.
Once a page is scanned and saved, wiping it with a damp cloth erases the FriXion ink and the page is ready to write on again. That's the entire loop: write, tag, scan, wipe, repeat, and it's the same reusability the Executive-size Core relies on, just applied across a bigger sheet of paper.
This generation of the Core also updates the paper itself. Rocketbook describes it as premium reusable paper with an improved pen-to-paper feel, paired with the redesigned scratch-resistant cover, which matters because the wipe-and-rewrite cycle only stays pleasant to write on if the paper holds up through repeated erasing without going slick or fibrous.
The reuse cycle is also the product's sustainability pitch. Rocketbook builds the Core around cutting down paper waste: one notebook stands in for a stack of single-use pads, since pages get erased and reused instead of torn out and thrown away once they're full.
Why the Letter Size Specifically: More Room Per Page
The Letter size's main advantage over the Executive version is straightforward: an 8.5 x 11 page holds roughly twice the writing surface of a 6 x 8.8 page, so notes that would need two or three Executive pages often fit on one Letter page. That matters most for people who draw wide tables, wireframe layouts, or take notes with a lot of side-margin annotations, where running out of horizontal space mid-thought breaks the flow.
It also matters for anyone digitizing whiteboard-style content. A full-page mind map or a project timeline with several parallel tracks reads better as one scanned image than as two or three smaller pages stitched together after the fact. If your handwriting runs large, or you're used to a standard legal pad, the Letter-size Core will feel closer to what you already write on than the more compact Executive format does.
Where the Rocketbook Core Letter Size Falls Short
The biggest tradeoff of the Letter size is the one built into its size: it doesn't fit as easily into a bag pocket, purse, or briefcase side sleeve the way the Executive size does, since it's a full 8.5 x 11 sheet rather than a compact 6 x 8.8 one. If portability is the priority over page space, that's a real cost to weigh.
- Reuse depends on using the included FriXion pen or a FriXion-compatible pen; a different pen may not erase cleanly
- Scanning quality and cloud routing depend on the Rocketbook app working correctly with your phone's camera and your cloud accounts
- Full-size pages mean it won't slide into a jacket pocket or a small bag the way the Executive size will
- It's a single-subject notebook, not a multi-tab binder, so heavy multi-project users may want more than one
- Pages are grid-only in this listing, which favors diagrams, tables, and structured notes over long-form free writing more than a blank or ruled page would
Rocketbook Core Letter Size vs the Alternatives
The clearest alternative to consider first is Rocketbook's own Executive-size Core, at 6 x 8.8 inches, which uses the same write-scan-erase system and the same app. It's a legitimate option for readers who want something more pocketable than a full Letter pad, and the tradeoff is straightforward: less writing room per page in exchange for a size that fits a bag side-pocket or a smaller bag entirely. Neither size is better outright; the choice comes down to whether you value page space or portability more.
Against traditional spiral and hardcover journals also selling in this category, the comparison is a different kind of tradeoff. A standard lined or hardcover spiral notebook, including hardcover options with removable tab dividers, costs less upfront and never depends on an app, a pen type, or a phone camera working correctly. What it can't do is come back to life once it's full: once the last page is written, that notebook is done, and any digital copy of your notes has to be typed or photographed by hand with no scan-to-folder routing built in.
- Choose the Rocketbook Core Letter Size if you want maximum page space and cloud-synced, reusable notes
- Choose the Rocketbook Core Executive Size if the same reusable system matters more than page space, and portability wins
- Choose a traditional spiral or hardcover notebook if you want the lowest cost and zero dependence on an app or a specific pen

Frequently Asked Questions
- Yes, for anyone who takes handwritten notes regularly and wants them backed up to the cloud without retyping them. The write, scan, and erase cycle is simple, the included Pilot FriXion pen writes like a normal pen, and the Letter-size page gives full-page notes and diagrams more room than the smaller Executive version.
- The Letter size measures 8.5 x 11 inches and the Executive size measures 6 x 8.8 inches, and both use the same reusable pages, the same Pilot FriXion pen, and the same Rocketbook app. The Letter size gives more writing room per page, while the Executive size is easier to carry in a bag or briefcase side pocket.
- The notebook ships with a Pilot FriXion pen, and it needs a FriXion or FriXion-compatible pen to work, because the erase step relies on that ink's heat-sensitive formula. A regular ballpoint pen will write on the page but won't wipe clean afterward.
- Wipe the page with a damp cloth once it's scanned and saved. The Pilot FriXion ink responds to that light friction and moisture by clearing off the page, leaving it ready to write on again.
- Yes, especially the Letter size. A full 8.5 x 11 page holds more of a long meeting's notes on one sheet than the smaller Executive page can, and Smart Tags let you route each meeting's scan straight to the right project folder without extra filing steps afterward.
- It can be, since one Rocketbook Core stands in for a stack of disposable notebooks over time. Rocketbook designs the Core around reducing paper waste: pages get wiped clean and rewritten instead of filled once and thrown away, which is the entire point of the erase-and-rewrite system.
