Circa is built for real work—portable when you’re in motion, expansive when you’re at your desk. Use this guide to compare the five core sizes so you can match your page canvas, cover footprint, and disc count to the way you plan, meet, and think.
The quick view: dimensions and fit
The cover footprints and disc counts below are based on Levenger’s size specifications; page dimensions reflect current refill listings.
Compare the five Circa sizes at a glance.
| Circa size | Refill page size (W × H) | Typical disc count | Overall cover size (W × H) | Best for |
|---|---|---|---|---|
| Jotlet | 3 × 5 in cards | 3 discs | 3 1/4 × 5 1/2–5 3/4 in | Palm‑sized quick capture, pocket or small pouch carry |
| Compact | 3 3/4 × 6 3/4 in | 7 discs | 4 7/8 × 7 in | Errands, minimalist travel logs, slim handbags and folios |
| Junior | 5 1/2 × 8 1/2 in | 8 discs | 6 1/2 × 8 1/2 in | Everyday work notes and meetings with easy bag carry |
| Midway | 7 × 9 1/4 in | 9 discs | 8 1/4 × 9 3/4 in | Roomier spreads without the bulk of Letter |
| Letter | 8 1/2 × 11 in | 11 discs | 9 1/4 × 11 1/4 in | U.S. Letter documents, project archives, desk use |
Why these numbers matter: Jotlet and Compact disappear in a pocket or small bag. Junior balances space and portability for most meetings. Midway gives you breathing room for multi‑section notes. Letter integrates with U.S. Letter handouts and reports—ideal if you regularly punch printouts.
Choose by use case
Quick capture and travel‑light days
If you jot fast and move fast, the pocketable Jotlet keeps friction low; it’s designed around standard 3 × 5 cards that pop in and out quickly. A colorful, toss‑in‑your‑bag option like the Circa Laguna Jotlets (set of 4) suits grocery lists, quick phone notes, or a traveler’s tiny log. For security lines and tight connections, Compact is small enough to live in a jacket pocket without bulking it out.
Everyday work notes and meetings
Junior (5 1/2 × 8 1/2 in pages) is the office workhorse: enough room for diagrams and action lists, easy to carry between conference rooms. Prefer a roomier canvas without moving up to Letter? Midway (7 × 9 1/4 in pages) is a refined in‑between that’s ideal for two‑column layouts or annotated agendas. The slim, smooth‑turning Circa Modern Sliver Foldover Notebook keeps meeting flow uninterrupted; pair your pages with structured refills like the Think • List • Plan Pad Trio when you want fast capture with built‑in prompts. For facilitation frameworks, see Meeting Mastery: Templates for Agendas, Decisions, and Next Actions (Download + Refill Picks) and team standards in Circa for Teams: Standardizing Templates and Kits for Departments & Workshops.
Document‑heavy roles and archival notes
For consultants, educators, and team leads who punch handouts or archive multi‑month projects, Letter is the natural match. It houses full U.S. Letter sheets while preserving Circa’s rearrangeable flexibility. A durable daily‑carry choice is the Circa Leather Foldover Notebook. For at‑a‑glance structure in Compact, Junior, Midway, or Letter, add the Circa Monthly Tabs and Pullout Calendar. If you regularly punch documents, setup tips in The Circa Punch Playbook: Turn Any Document into Circa (Home, Office, Travel) can help.
Capacity, discs, and growth
Each Circa size scales from slim carry to project binder by changing disc diameter. If page turns feel tight or you’re adding dividers, upgrade to smoother, larger discs such as Matte Aluminum Circa 1" Discs for added capacity and glide. Disc counts by size—3 (Jotlet), 7 (Compact), 8 (Junior), 9 (Midway), 11 (Letter)—ensure stability across each format.

Hands, posture, and writing comfort
Size affects ergonomics: smaller formats shine for stand‑up notes or tight spaces; larger pages reduce flipping during long work sessions. Left‑handed writers often favor Junior or Midway for generous margins when the cover is folded back.

Which size fits common bags?
- Clutches and small crossbodies: Jotlet or Compact.
- Totes, messenger bags, and mid‑size backpacks: Junior or Midway.
- Briefcases and full‑size backpacks: Letter (plus project dividers, pockets, and punched documents).
Decision matrix: pick by priority
Use this compact comparison to map size to your top constraint.
| Priority | Strong fits | Tradeoffs to expect |
|---|---|---|
| Smallest carry | Jotlet, Compact | Limited drawing space; fewer pages before a disc upgrade |
| Everyday balance | Junior | Occasional page flips for wide agendas or mind maps |
| Larger writing canvas | Midway | Not compatible with full U.S. Letter printouts |
| Native with U.S. Letter documents | Letter | Heavier in small bags; best for briefcases/backpacks |

Planner fit by size
Monthly, weekly, and daily refills are available in Compact, Junior, Midway, and Letter. If you plan a whole year by the day, consider larger discs; quarterly sets keep weight down.

Budget, value, and smart ways to save
Levenger focuses on materials and engineering, so covers and discs are built to last—often more cost‑effective over time than replacing disposable notebooks.

Care, refresh, and archiving
Rotate sections seasonally and rebuild your Circa when projects turn over. Many professionals keep a portable Junior or Midway for active work and a Letter archive at the desk. For refresh routines—including tab swaps and off‑season storage—see Maintenance & Refresh: Archiving, Rebuilding, and Seasonal Planner Swaps.

Frequently Asked Questions
Which Circa size works best with U.S. Letter printouts?
Choose Letter if you frequently punch handouts or file documents without trimming; it matches 8 1/2 × 11 in pages and uses 11 discs for stability.
Is Midway compatible with most meeting agendas?
Yes—Midway’s 7 × 9 1/4 in page gives extra width for annotated agendas or two‑column layouts while remaining bag‑friendly. If you later need to merge printouts, keep a Letter archive at your desk.
How do I increase capacity without changing sizes?
Swap in larger‑diameter discs; it’s the fastest way to grow page count while keeping the same cover size. Many users upgrade to metal for smoother page turns, like the Matte Aluminum Circa 1" Discs.
What’s the lightest setup for a commute or conference?
Carry a Compact or Junior with thinner sections and pocket cards for quick capture. For travel days, the Circa Up and Away Discbound Notebook keeps things cheerful and easy to spot in a crowded tote.
