Half Letter paper measures 5.5 x 8.5 inches, or 139.7 x 215.9 mm. It is exactly half of US Letter, so one 8.5 x 11 inch sheet can be cut into two Half Letter pages.

Use the Half Letter paper size reference when you need the dimensions first. Use this guide when you are deciding how to print, trim, punch, bind, or design compact pages that still feel familiar to US printers.

Quick answer

Half Letter is best for compact printables that need more writing room than an index card but less bulk than a full Letter sheet. Common uses include:

planner inserts
disc-bound notebook pages
compact meeting notes
habit trackers
portable checklists
field notes
booklet pages
small handouts

It is not the same as A5. A5 is 148 x 210 mm, while Half Letter is 139.7 x 215.9 mm. The two sizes are close enough to cause confusion, but not close enough to mix casually in fitted covers, punched planners, or page templates.

Half Letter vs Letter

Half Letter keeps the same width family as US Letter because it is made by cutting Letter in half along the long direction. A full Letter sheet is 8.5 x 11 inches. Half Letter is 5.5 x 8.5 inches.

That relationship makes DIY printing practical. You can print two Half Letter pages on one Letter sheet, cut down the middle, and end with two compact pages. This is why Half Letter appears often in planner communities, home binders, and printable insert systems.

The tradeoff is usable space. A page that feels open on Letter can become crowded on Half Letter once you add rings, discs, crop marks, headers, or a left margin. Half Letter rewards tight hierarchy: short labels, fewer decorative blocks, and clear writing zones.

Half Letter vs A5

Half Letter and A5 are often treated as interchangeable because both are small notebook-friendly sizes. They are different standards.

Size	Inches	Millimeters	Notes
Half Letter	5.5 x 8.5 in	139.7 x 215.9 mm	Half of US Letter, common in US planner inserts
A5	about 5.83 x 8.27 in	148 x 210 mm	ISO size, common outside North America
Junior Legal	5 x 8 in	127 x 203.2 mm	Smaller US office size, less common

If you are buying covers, binders, or pre-punched inserts, do not rely on the name alone. Measure the page and check the hole pattern. A5 paper may fit loosely in some Half Letter covers, but punched holes and tab positions may not line up.

When Half Letter is the right choice

Choose Half Letter when the page needs to travel, be handled often, or fit inside a compact planner. It works well for pages that capture decisions, lists, or routines rather than dense long-form writing.

Good Half Letter candidates include daily task sheets, weekly checklists, meeting capture pages, project inserts, recipe planning pages, field forms, and travel notes. These pages benefit from being smaller because they are used repeatedly and moved between desk, bag, and binder.

Avoid Half Letter when the page needs large tables, long paragraphs, wide diagrams, detailed math work, or generous handwriting space. In those cases, Letter, Legal, A4, or 11x17 may be easier to read and print.

Printing two-up on Letter

The most economical workflow is two-up printing:

Design each finished page at Half Letter size.
Place two pages on one Letter sheet.
Print at 100% scale.
Cut the sheet at 5.5 inches.
Punch or bind only after confirming the trim.

This workflow is cleaner than designing a full Letter page and shrinking it afterward. Shrinking can make ruling, margins, and type too small. For templates, forms, and planner inserts, design at the finished size first.

If your software supports N-up printing, check the preview carefully. Some print dialogs add spacing, rotate pages unexpectedly, or scale down to printable area. If the page must preserve exact dimensions, export an imposed Letter PDF with two Half Letter pages already placed.

Paper stock and cutting workflow

Ordinary 20 lb or 75 gsm office paper is fine for draft inserts, but planner pages that will be handled every day usually feel better on slightly heavier stock. Heavier paper reduces show-through from pens and makes punched edges more durable. Test the paper weight with your printer before buying a full ream, especially if you plan to duplex print.

For cutting, use a trimmer with a fixed guide instead of scissors. A tiny angle error on one sheet becomes visible when many pages are stacked together. Cut one test sheet first, place it in the cover or binder, then use that sheet as the reference for the rest of the batch.

If you are printing dated pages, do not batch the whole year until the first week has been written on, turned, and carried around. Half Letter pages are small enough that a margin or ruling problem becomes annoying quickly.

Margins, rings, and disc binding

Binding is where many Half Letter layouts fail. Rings and discs take real space. A margin that looks comfortable on screen can feel tight once the page is punched and placed in a planner.

For ring binders, leave a wider inside margin than you think you need. For disc-bound pages, test with the exact punch and discs you plan to use. Discs can make left-page writing awkward if the writing column starts too close to the punched edge.

Before making a full planner, print one two-up proof. Cut it. Punch it. Put it into the actual cover. Then write near the inner edge on both left and right pages. That test reveals whether the margin works better than a ruler measurement alone.

Duplex and alignment checks

Two-sided Half Letter printing is useful for planners and booklets, but it adds alignment risk. Small shifts that are invisible on Letter can look obvious once the sheet is cut.

Print one duplex test sheet before a batch. Add a border, crop marks, and a light center line. After cutting, compare the front and back margins. If the back side drifts, adjust the layout or print one-sided.

For booklet pages, make sure page order is imposed correctly before cutting or folding. The first and last pages may need to share a sheet, depending on whether you are building a booklet, a planner stack, or loose inserts.

Design rules for readable Half Letter pages

Half Letter works best when every section has a job. Keep headings short. Use fewer columns. Avoid large decorative headers that steal writing space. Put the most repeated action near the top, such as the date, task list, or meeting topic.

For lined or dot-grid pages, avoid spacing that is too tight. A compact page does not automatically need tiny ruling. If users write quickly, comfortable spacing matters more than maximizing line count.

For checklists, keep boxes large enough to mark with a pen. For trackers, limit the number of rows. For meeting notes, give the main note area more room than metadata fields.

Is Half Letter the same as A5?

No. A5 is 148 x 210 mm. Half Letter is 139.7 x 215.9 mm. They are similar, but covers, punched holes, and templates may not align.

Can I print Half Letter on a normal printer?

Yes. The easiest method is to print two Half Letter pages on one Letter sheet, then cut the sheet in half. Some printers can also feed smaller paper directly, but two-up Letter printing is usually more reliable.
