Link or textA URL, phone number, Wi-Fi string or plain message. Longer payloads need a denser code, which means smaller squares to print.Words on the tag1 to 24 characters, set in Barlow Condensed, a narrow sans that fits a long name across the tag.

Label position

Reads as a caption, and keeps the type furthest from the keyring lug.

Type size9 mm

The em size, so the letters come out a little shorter than this. Bigger type means thicker strokes; if the letters get too fine to print, the generator says so.

Space to the code0 mm

Blank plate between the words and the code. 0 puts them flush against it.

Space to the edge3 mm

Blank plate between the words and the tag's edge.

Code size40 mm

The width of the tag, and what the code is sized from. The words add a band below or above the code, so the finished tag is taller than this.

Extra border2.5 mm

Blank plate around the code, on the three sides the words are not on. On the words' side there is none — that space is “Space to the code” above.

Corner radius3 mm

Error correction

Plate thickness2 mm

Raised height1.2 mm

How far the code squares and the letters stand off the plate. They are one part in one colour, so they share it.
