i built a free dtf cost tool because "per inch" math is a lie
Honestly, I’ve seen how much of a pain it is to get a straight answer on what a transfer actually costs. My wife has an online store, and whenever we looked at calculators, they were either trying to upsell us on a specific shop's sheets or they used "per square inch" math.
The square inch math is basically a lie because it doesn't account for wastage. If you can’t fit that last row of logos on a 22" roll, you're still paying for that empty space anyway.
I’m a dev, so I spent a few nights putting together a tool called InchWise to fix this. It’s free and doesn’t require an account or anything.
A few things I made sure to include:
True Cost: You put in the actual price you pay for a full sheet/roll so you see the real margin, wastage included.
Privacy: Everything happens locally in your browser. No artwork ever gets uploaded to a server— which was a huge requirement for her designs.
Neutral: It isn't tied to any specific print shop.
If it helps anyone else get quotes out faster, feel free to use it.
