Choosing size depends on what you’re labeling and how you print.

• Address labels: about 1 x 2-5/8 inches, often 30 per sheet.
• Shipping labels: 2 x 4 inches or half-sheet 8.5 x 5.5 for larger info.
• Full sheet labels: 8.5 x 11 inches to cut custom shapes.
• 4 x 6 labels: a common shipping format on sheets or thermal rolls.
• Specialty shapes: squares, rectangles, circles, and disc labels for products.

Measure the space on your envelope, package, or product, then match dimensions and the sheet layout you prefer. If you’re covering old markings, look for opaque backing. You can filter by size and printer type on Walmart.com and choose pickup or delivery where available.

Compatibility comes down to your printer type and the label material.

• Most sheet labels list laser and inkjet compatibility. Check the product details.
• Some waterproof inkjet sticker papers are designed for inkjet only.
• Certain blockout or specialty materials may be laser only.
• Direct thermal labels (commonly 4 x 6) work with thermal label printers, not standard desktop printers.

Before printing, select the correct paper size (Letter or A4) and consider a media setting like Labels or Heavyweight if your printer offers it. Printing a test page on plain paper can help confirm alignment. Availability and settings vary by printer, so refer to your printer’s guide for best results.

A few setup tweaks can help reduce jams and improve alignment.

• Store label sheets flat in a cool, dry place; avoid humidity and curl.
• Fan the stack and feed one sheet at a time using the manual tray if available.
• Use a template that matches your sheet layout (for example, 30-up or 10-up).
• Print a test on plain paper, hold over the label sheet, and check alignment.
• Set scale to 100 percent and the correct paper size; avoid Fit to Page.
• Choose a Labels or Heavyweight media type if offered, and let ink dry before handling.
• Avoid reusing partially printed sheets, which can increase the chance of jams.

Labels vary by adhesive and face material, which affects use and removal.

• Permanent adhesive: sticks firmly to cardboard, paper, and many plastics; not intended for clean removal.
• Removable or repositionable: peels off more easily and can be adjusted shortly after application.
• Waterproof materials: resist moisture and smudging; some are laser compatible, others are inkjet specific.
• Opaque or blockout backing: helps cover old text or barcodes underneath.
• Rounded corners: can reduce edge lift on boxes and mailers.

Match the label to your surface and conditions (indoor, outdoor, cold, or damp). Testing a small area first is a practical way to gauge adhesion and print results.

Most label sheets work well for barcodes and QR codes when printed clearly.

• Choose a matte white label for strong contrast and reliable scanning.
• Use at least 300 dpi for barcodes and 600 dpi for dense QR codes.
• Print at 100 percent scale; avoid Fit to Page or any resizing.
• Leave a quiet zone (blank space) around the code per your standard.
• Pick a label size that keeps codes large enough to scan easily.
• Test with a scanner or scanning app before mass printing.
• Direct thermal 4 x 6 labels can produce crisp black codes with compatible thermal printers.

Standards vary by system, so follow any size or formatting guidance from your platform.
