Half of a standard 8.5 x 11 inch (US Letter) sheet measures 8.5 x 5.5 inches, often called half letter or half-sheet.

• How to get it: Buy pre-cut half letter packs, or use 8.5 x 11 paper with a center perforation you can separate after printing.
• Typical uses: Handouts, memos, mailers, and tax statements like W-2s or 1099s.
• Printing tip: In your print dialog, choose “2 per page” on letter paper, or set the paper size to 5.5 x 8.5; specific options can vary by printer and software.

“Half-size” can mean a couple of different formats, depending on what you need:

• Half Letter (US): 8.5 x 5.5 inches.
• A5 (International): 148 x 210 mm (about 5.83 x 8.27 inches).

Both options are common on this page. Half letter pairs well with US 3-ring binder and memo accessories, while A5 lines up with many planner systems and international templates. When choosing, consider the layout you’ll print, the binder or clipboard you use, and your printer’s supported sizes to help ensure a smooth setup.

Half of A4 is A5 in the ISO paper system.

• A4: 210 x 297 mm
• A5 (half A4): 148 x 210 mm (≈ 5.83 x 8.27 inches)
• B5: 176 x 250 mm (between A4 and A5 in size)

If you’re splitting A4 documents or using A-series templates, A5 is the direct match. B5 can be helpful when you want something slightly larger than A5, but it won’t equal a true half of A4. For best results, align your document and printer settings to the exact size you plan to use.

They’re different sizes, so it helps to pick based on your project.

• Half Letter: 8.5 x 5.5 inches (US standard).
• A5: 148 x 210 mm (about 5.83 x 8.27 inches).

Half letter is wider and a bit shorter than A5. US binders, clipboards, and many templates favor half letter, while A5 is common in planners and international layouts. Most printers offer custom sizes, but capabilities vary. A quick test print on the exact paper size you’ll use can help dial in margins and orientation before larger runs.

Many home and office printers can handle these sizes, but support varies by model.

1. Check your printer manual or driver for supported sizes.
2. In Page Setup, select “5.5 x 8.5” (Half Letter) or “A5.”
3. Load paper in the manual feed or adjust the side guides snugly.
4. Choose “Actual size” and the correct orientation to avoid scaling.
5. Print a short test page; tweak margins if you notice clipping.

If your device doesn’t list smaller sizes, consider using perforated 8.5 x 11 sheets and printing two-up, then separating after. This approach can be a practical workaround.
