Why 85.6 × 54 mm is the size to aim for
That is the ISO ID-1 credit-card footprint, and it happens to be the size most luggage loops, badge holders, and travel wallets are built around. A tag at that size slides into a loop without folding, and it is large enough for a bold surname and a two-color mark.
The generator’s native footprint maxes out near 96 mm, so a card-size tag is a modest 0.89× downscale rather than an upscale. That keeps the hole, wall thickness, and color steps at their designed proportions.
