Find the tape widths listed for your Brother printer
Check the full model on the label maker’s base or back. The model tells you which cassette family it uses and what widths it accepts. The name on the front can help identify the range, but P-touch CUBE alone leaves two common possibilities with different width limits.
| Brother model | Listed TZe widths | TZe-221, 9 mm | TZe-231, 12 mm |
|---|---|---|---|
| PT-H110 | 3.5, 6, 9 and 12 mm | Yes | Yes |
| PT-P300BT CUBE | 3.5, 6, 9 and 12 mm | Yes | Yes |
| PT-P710BT CUBE Plus | 3.5, 6, 9, 12, 18 and 24 mm | Yes | Yes |
| PT-D610BT | 3.5, 6, 9, 12, 18 and 24 mm | Yes | Yes |
| PT-P910BT CUBE Pro | 3.5, 6, 9, 12, 18, 24 and 36 mm | Yes | Yes |
The width column describes available nominal widths across compatible supplies. The 3.5 mm tape listed for several of these models is a specific narrow option. Use the model’s own list for individual materials, adhesive types and colours at each width.
If you own a PT-H110 and a PT-P710BT, you can share the featured 9 mm and 12 mm cassettes between them. Keep 18 mm and 24 mm cassettes with the Plus. That makes it easier to restock a shared cupboard without sending someone to the wrong machine with a wide tape.
Identify the cassette family before checking width
Look for the full TZe or older TZ marking and cross-check the manual for the exact printer. Brother describes compatible TZe refills for P-touch printers marked TZ or TZe. Its current product range also includes P-touch branded machines with other supplies, so the logo and the manufacturer list carry more weight than the P-touch name alone.
For example, the PT-N10, PT-N20 and PT-N25BT take Brother Btag tapes. They use a 12 mm format of their own. A QL desktop label printer uses a DK roll and holder with model-specific widths. If a machine takes another family such as Brother M tape, start in that family’s consumables list.
In the catalogue, start with Consumables & Accessories for the printer, then open the tape list. Find the complete code you intend to buy. A listing that only says “for Brother” or “12 mm cartridge” leaves out the distinction that determines whether it fits.
Choose a complete code and a usable width
TZe-231 is a genuine Brother laminated cassette with black print on white tape, 12 mm wide and 8 m long. This is a useful repeat purchase for filing, drawers and storage boxes with enough flat space. Measure the section where the adhesive will sit, especially if the folder has a lip or the drawer has a moulded edge.
12 mm · everyday labels
Brother TZe-231 laminated tape
A genuine 12 mm cassette for black text on white laminated labels. Useful when a folder spine, drawer or box face has room for larger type.
Keep in mind. Check that Brother lists the cassette for your P-touch model. Measure the flat space first if you are labelling narrow tabs or dividers.
- 12 mm × 8 m
- Black on white
- One laminated cassette
TZe-221 uses the same black-on-white laminated format and length in a 9 mm width. Choose it for a short identifier on a narrow divider or folder edge. Before ordering a second width, try laying a plain paper strip cut to size on the actual surface. It will show whether the label can sit flat with room around the edges.
9 mm · narrow edges
Brother TZe-221 laminated tape
A genuine 9 mm cassette with black text on white laminated tape. It fits narrower folder spines, dividers and drawer lips where a 12 mm strip would overhang.
Keep in mind. Choose a short, readable design for the smaller printable area. Brother lists this cassette for specific P-touch models.
- 9 mm × 8 m
- Black on white
- One laminated cassette
Choose material and adhesive after checking fit
Keep the letters in the code when comparing tape. A TZe-231 and a TZe-N231 share width and colour, while the N version has a non-laminated finish. Brother also distinguishes standard laminated, stronger adhesive and flexible identification tape. Look for the product name and technical details alongside the code, especially when a listing groups variants under one photograph.
For ordinary filing on a clean, flat spine, standard laminated tape gives you a readable label with a protected print layer. For a cable or a difficult textured surface, consult Brother’s tape selection guide and verify the specific cassette in the machine’s list. A wider version of the same standard cassette changes the label dimensions. A specialist adhesive or flexible material changes how the label behaves on the surface.
Nominal tape width describes the strip edge to edge. The machine leaves a margin at the top and bottom, so allow for its printable height when deciding how many lines will fit. Preview a real label at the size you intend to use. Shortening a folder name is often more readable than reducing all the text to fit a narrow strip.
Load one cassette and print a short sample
Follow the loading diagram for your model. When replacing a cassette, check that the tape end follows the guide and that the cassette is seated in the orientation shown. Close the cover normally and use any model-specific feed instruction before printing. Keep the old cassette code if you want to buy the same finish and width again.
On a phone or desktop model, check the design’s tape width after changing stock. A saved 24 mm layout may need to be resized or simplified when you swap to 12 mm tape. Print one short sample, place it on the intended surface and confirm that the text is readable and the edges sit flat before printing a batch.

Common questions
Does Brother TZe-231 fit the PT-H110?
Yes. Brother lists TZe-231, a 12 mm black-on-white laminated cassette, for the PT-H110. The same model also lists the narrower 9 mm TZe-221.
Can the smaller P-touch CUBE take 18 mm tape?
The PT-P300BT takes TZe widths up to 12 mm. Choose a listed wider model such as the CUBE Plus PT-P710BT if you need 18 mm.
Does 12 mm TZe tape fit a Brother PT-N25BT?
The PT-N25BT uses 12 mm Brother Btag cassettes. Check the Btag marking when ordering for the PT-N25BT, PT-N20 or PT-N10.
Can I use TZe tape in an older Brother printer with a TZ logo?
Brother describes TZe tapes as suitable for supported printers marked TZ or TZe. Check the exact model’s consumables list and the cassette width before ordering. Older P-touch machines can use different tape families.
Does TZe-N231 have the same finish as TZe-231?
They share a 12 mm width and black-on-white colours. Brother lists TZe-N231 as non-laminated and TZe-231 as laminated, so check the complete code before buying a replacement.
