How are you sizing labels for round jars vs. straight-sided jars?
Label sizing gets a little more complicated once the container has a curve.
With straight-sided jars, you can measure the usable panel fairly directly. Round jars are less forgiving. A label that looks right on a flat template can wrinkle, overlap, or lift once it’s wrapped around the circumference.
For round jars, an easy way to find the usable width is to wrap a seamstress measuring tape around the straight section of the jar. No measuring tape? A strip of paper works too. Wrap it around the jar, mark where it meets, then measure the strip flat. Just don’t assume the full circumference should become your label width. Leaving a small gap at the back makes application easier and avoids overlap or buckling.
Also think about how much of the label should be visible from the front. If your product name or key information is spread too far around the curve, customers may have to rotate the jar just to read it. Sometimes a slightly narrower front label works better than using every available inch.
For those labeling candles, sauces, cosmetics, etc., what’s your rule of thumb?
