The best extra large whiteboard calendar depends on how much writing room and planning detail you need. The 38-by-50-inch Party Funny Store calendar is best for oversized day-by-day planning, while the BooQool 40-by-28-inch calendar offers flexible undated monthly layouts. For a framed magnetic board, consider CALENBO, JILoffice, or Comix; Comix is the largest of these framed monthly boards.
| Calendar | Size | Best For |
|---|---|---|
| Party Funny Store | 38 x 50 inches | Large daily writing areas and weekly planning |
| BooQool | 40 x 28 inches | Undated, flexible monthly planning |
| CALENBO | 36 x 24 inches | A framed board with included accessories |
| JILoffice | 36 x 24 inches | Magnetic notes and monthly scheduling |
| Comix | 36 x 48 inches overall | A large framed magnetic monthly planner |
Party Funny Store 38 x 50 Calendar

This calendar is best for households, teams, or offices that need very large daily writing spaces. At 38 by 50 inches, it is the biggest listed option by overall dimensions. The product includes a yearly calendar and an erasable weekly planner, giving users more than a basic monthly grid.
Each date square measures 6.5 by 5.5 inches and is divided into seven parts for writing plans. Its treated reusable film is described as smooth and compatible with whiteboard, dry erase, and chalkboard markers. Choose this if daily details and weekly planning matter more than a framed magnetic-board format.
Consider: Its large footprint requires substantial wall space. Measure the intended location before choosing it.
BooQool Undated 40 x 28 Calendar

The BooQool calendar is best for buyers who want a large monthly planner they can start at any time. Its undated layout avoids fixed month and year assignments, making it useful for rotating schedules or planning periods that do not begin in January.
The 40-by-28-inch surface has daily blocks measuring 5.4 by 3.7 inches, with seven ruled lines in each block. The printed lines are designed to make entries easy to see at a glance. Ten round stickers are included, according to the product listing. Choose this if you value flexible monthly scheduling and clearly divided writing areas.
Consider: Because the calendar is undated, you need to fill in the dates yourself.
CALENBO 36 x 24 Magnetic Calendar Board

This framed monthly whiteboard is best for buyers who want a ready-to-use kit. It includes two magnetic erasers, six magnets, ten markers, a pen tray, and a mounting kit. Its magnetic writing board has a smooth, scratch-resistant surface and an aluminum frame with protective plastic corners.
The monthly grid has six lines, which the listing says accommodates full months from January through December. The pen tray keeps supplies close by and helps keep them from covering calendar entries. Choose CALENBO if included markers, magnets, and mounting hardware are priorities.
Consider: At 36 by 24 inches, it is smaller than the 38-by-50 and 40-by-28 options, so its overall planning area is more limited.
JILoffice 36 x 24 Magnetic Month Board

The JILoffice board is best for users who want to combine a monthly calendar with magnetic notes and documents. Its magnetic surface can hold items such as notes, pages, photos, cards, and graphs, according to the product details. The board is also described as having a smooth, scratch-resistant surface that wipes clean with dry erase markers.
A satin black aluminum frame, detachable marker tray, and rounded nylon corners complete the design. Choose this model if using magnets to display reminders alongside the schedule is more important than having the largest available calendar. The listing does not specify included markers or magnets.
Consider: Its 36-by-24-inch size offers less surface area than the larger wall planners in this list.
Comix 48 x 36 Magnetic Monthly Planner

Comix is best for buyers who want a large framed monthly board with a magnetic writing surface. Its overall dimensions are 36 by 48 inches, including the frame. The six-line layout is designed to fit full months from January through December, making it a useful option for work, school, or household scheduling.
The smooth surface is described as easy to write on and wipe clean. Durable hooks and wall-mounting screws are included for horizontal installation. Choose this if you want a larger framed monthly calendar and mounting hardware in the package.
Consider: This is a monthly planner, not a listed weekly planner with separate weekly scheduling space.
Buying Guide: How To Choose An Extra Large Whiteboard Calendar
How much wall space do you have?
Compare the stated dimensions with the open wall area, allowing room around the calendar to write and erase. The Party Funny Store calendar measures 38 by 50 inches, while BooQool measures 40 by 28 inches. The framed Comix board is 36 by 48 inches overall. Check whether a listed measurement includes a frame when that information is provided.
Do you need a monthly, weekly, or flexible layout?
Choose a monthly board for appointments and schedules that need to be visible at a glance. The Party Funny Store option also includes a weekly planner. BooQool is undated, so it can be started in any month, but users must enter the dates. Framed CALENBO, JILoffice, and Comix options are presented as monthly boards.
How much writing space does each day need?
Look for block measurements and ruled lines, not just total board size. Party Funny Store lists 6.5-by-5.5-inch date squares, while BooQool lists 5.4-by-3.7-inch daily blocks with seven ruled lines. If several people will share a calendar or entries need detail, larger date cells may be more practical.
Should you choose a magnetic board or an erasable film calendar?
A magnetic board can hold notes or documents as well as written plans; JILoffice specifically describes magnetic use. A reusable film calendar may suit buyers focused on large writing areas and flexible planning. Review each product’s listed accessories and mounting details rather than assuming every model includes markers or magnets.
