4x6 labels measure 4" x 6", the standard size for UPS, FedEx and USPS shipping labels printed on thermal printers. Ecommerce sellers, warehouses, distribution centers and manufacturers use them for shipping labels, packing slips, and case and pallet labels. Smith Corona makes these labels and sells them factory-direct at wholesale prices. Choose direct thermal, thermal transfer or inkjet rolls on 0.75", 1", 2" or 3" cores, or fanfold stacks, in paper, polypropylene and colors.
If you are unsure which side is your label's width, just look at how it exits your printer.
The green arrows indicate the width of your label.
If you are unsure which side is your label's length, just look at how it exits your printer.
The green arrows indicate the length of your label.

A 4x6 label is 4" wide and 6" long (101.6 x 152.4 mm). It is the format UPS, FedEx, USPS and shipping software default to for thermal printers, and it fits any printer with a 4" print width. Smith Corona makes 4x6 labels in three print technologies: direct thermal, which needs no ribbon; thermal transfer, which prints through a ribbon; and inkjet, for color label printers.

4x6 labels cover most jobs on a shipping dock, and one printer and one roll can run all of them. The most common is the carrier shipping label printed from software and marketplaces such as ShipStation, Shopify, Amazon, eBay and Etsy. Shippers also print 4x6 packing slips, case and carton labels, GS1-128 compliance labels, pallet labels and receiving labels. Labels that have to last, such as pallet labels stored outdoors or product labels on a shelf, print on thermal transfer.
| Printer class | Examples | Core | Roll OD | Labels per roll | Per case |
|---|---|---|---|---|---|
| Mobile | Zebra ZQ and QLn series | 0.75" | 2.2" / 2.6" | 85 / 105 | 42 / 32 rolls |
| Desktop | Zebra GK and ZD series, Honeywell PC42 | 1" | 4" | 250 | 16 rolls |
| Desktop XL | Zebra GK and ZD series | 1" | 5" | 475 | 12 rolls |
| Industrial | Zebra ZT, Datamax I-Class, Sato CL4NX | 3" | 8" | 1,000 | 4 rolls |
| Print and apply | Applicators and high-volume lines | 3" | 12" | 2,900 | 2 rolls |
| Fanfold | Desktop and industrial printers with a rear feed slot | — | — | 2,000 per stack | 2 stacks (4,000) |
| Color inkjet | Epson ColorWorks, Afinia, Primera | 2" or 3" | 4", 6" or 8" | 163 to 980 | Varies |
Desktop printers hold a roll no larger than 5" OD. An 8" industrial roll won't fit, even in desktop models that take a 3" core adapter. Fanfold feeds from a 2,000-label stack behind the printer, more than four times what a 5" desktop roll holds.
The most common ordering mistake is reversing width and length. Width runs across the printhead.
Thermal 4x6 labels come with any of Smith Corona's four adhesives:
Yes. 4" x 6" is the standard thermal shipping label size for UPS, FedEx and USPS, and shipping software and marketplaces such as ShipStation, Shopify, Amazon, eBay and Etsy all print it.
Yes. Carriers require a label that scans, not a branded one. Plain white 4x6 labels, direct thermal or thermal transfer, work for every carrier, so one roll covers UPS, FedEx and USPS shipments.
Yes. Many shippers print packing slips, case labels and pallet labels on the same 4x6 roll as their shipping labels, so one printer handles the whole order. Shipping platforms such as ShipStation offer a 4x6 packing slip layout.
Thermal transfer printing uses a ribbon. A heated printhead melts pigment from the ribbon onto the label, producing an image that resists heat, light, moisture, chemicals, and abrasion. Direct thermal printing uses no ribbon; the label stock itself is heat-sensitive and darkens where the printhead touches it. Direct thermal is simpler to run, but the image fades with exposure to heat, sunlight, and friction. Thermal transfer labels hold their printed image for years in service; direct thermal labels are generally rated 6 to 12 months.
Not rolls or fanfold. Office laser and home inkjet printers feed 8.5" x 11" sheets, so they need 4x6 sheet labels. Smith Corona's 4x6 inkjet roll labels are made for color label printers such as Epson ColorWorks, not home inkjet printers.
Yes. Smith Corona manufactures its labels at its own facility in Cleveland, Ohio. Adhesive is formulated in-house, and label stock is coated and converted on site.
It depends on the roll OD: 250 on a 4" desktop roll, 475 on a 5" desktop roll, 1,000 on an 8" industrial roll and 2,900 on a 12" roll. Mobile rolls hold 85 or 105 labels, and a fanfold stack holds 2,000, two stacks to a case.
Usually, yes. Smith Corona lists width first, so a 4" x 6" label runs 4" across the printhead and 6" through the printer. A label that is truly 6" wide needs a 6" wide printer.
Yes. Smith Corona manufactures 4x6 labels and sells them factory-direct by the case, so you pay wholesale pricing with no distributor markup. See why our labels cost less. Most 4x6 cases hold 4,000 to 5,800 labels, the minimum order is one case, and every format has volume price breaks.
Yes. Smith Corona can make labels in any width and length, in any of its materials, colors and adhesives, and can match any PMS color. Non-stock orders typically carry a minimum of 15 cases or $1,500 and ship in three to four weeks. For labels that arrive already printed with your logo or text, see custom labels.
Smith Corona makes direct thermal and thermal transfer 4x6 labels in white and 16 colors: yellow, blue, dark blue, green, chartreuse, orange, red, pink, hot pink, purple, grape, brown and gray, plus fluorescent red, green and orange. Orange, yellow, green and blue direct thermal 4x6 labels are stocked. Other colors are made to order, typically with a 15-case or $1,500 minimum and a three to four week lead time, and any PMS color can be matched.
Paper 4x6 labels are not waterproof. Top-coated direct thermal stock adds some resistance to moisture and oils. For labels that get wet, use polypropylene thermal transfer or inkjet labels, which are water-resistant.
Yes, with Freezer Grade adhesive, rated from -40°F to 32°F. Smith Corona makes 4x6 freezer labels in direct thermal and thermal transfer, in every roll format and fanfold. General Purpose adhesive is rated only down to 32°F.
Yes. Smith Corona direct thermal and thermal transfer labels are made on phenol-free facestock, so they contain no BPA, BPS or other phenol developers. Many thermal papers use BPA or BPS in their heat-sensitive coating.
Any thermal printer with a 4" print width. Fit comes down to core size and roll OD, so check your model on the shop-by-printer pages.
No. Zebra printers run any 4x6 label with the right core size, roll OD and technology. After loading a new brand of label, run a media calibration so the printer finds the gap or black mark between labels.
Open the printer and look for a ribbon carriage — two spindles that hold a supply roll and a take-up roll. If they are present, the printer supports thermal transfer. If there is only a path for the label roll, it is direct thermal only. You can also test the labels themselves: drag a coin edge or fingernail firmly across the label face. Direct thermal stock darkens where the friction generates heat. Thermal transfer stock does not mark.
The printer hasn't calibrated to the label length. Run a media calibration, and recalibrate whenever you change label size or brand.
Either thermal transfer labels are loaded in a direct thermal printer, or the roll is loaded with the label face away from the printhead. Thermal transfer labels have no heat-sensitive coating and print only through a ribbon. Check the label with the fingernail test, then reload the roll so the label face meets the printhead.
Usually the print is too faint or the label was shrunk to fit. Raise print darkness or lower print speed, clean the printhead with isopropyl alcohol, and print at 100% so the barcode keeps its full size.
The minimum order for stock 4x6 labels is one case. Made-to-order sizes and colors typically carry a minimum of 15 cases or $1,500.
Stock 4x6 label orders placed by 4:00 PM EST ship the same business day from Smith Corona's Cleveland, Ohio facility. Custom and made-to-order sizes ship in three to four weeks.
No. Smith Corona does not offer free shipping on labels or ribbons; shipping is calculated at checkout. See the Smith Corona shipping policy.
Yes. Larger orders ship LTL freight, which is usually cheaper per case than UPS or FedEx Ground and arrives palletized and shrink-wrapped. As a rule of thumb, orders over 15 cases qualify. Shipping options, including LTL, are shown at checkout. If you're not sure your order qualifies, use the Estimate Shipping button on the product page or in your cart.
Yes. Provide your UPS or FedEx account number, or a customer-provided BOL for LTL-sized orders.
