How do I test if my skate ski camber matches my weight?

The paper test is the standard method: place the ski on a flat, hard surface, stand on it with your full weight evenly distributed on both skis, and have someone slide a piece of paper under the ski. The paper should slide freely from tip to tail with full weight on both skis. Then shift all weight to one ski—the paper should be trapped and unable to move, indicating the ski has compressed to full snow contact. If the paper slides freely on one ski, the camber is too stiff. If it's trapped on both skis, the camber is too soft. Professional shops can perform more precise camber testing.
