1 Decide how much you want to hem your jeans. Try on jeans and decide which length suits you. Usually jeans should not reach the floor by 2.5 cm - this prevents them from fraying, and the size does not look too small. However, you can choose the length according to your own preferences.

2 Roll up the bottom. Make a cuff where you want to tuck the jeans and fold in a fold. Then measure from the current edge to the crease and make a similar crease on the other leg.

3 Secure the lapel. Pin the fabric with straight pins around the circumference to hold it in place. Check the seams - they should be the same on both legs.

4 Hem. Make a circular seam just above the existing seam. This can be done either on a typewriter or by hand. It's about hemming the cuff from the inside out and then turning it inside out, this will allow you to release the length back if you grow over time or just want a longer pair of jeans.

5 Straighten the fold. Tuck the excess folded cuff fabric into the pant leg, folding the original seam down to reveal the outside of the leg again. You will be left with a small fabric loop inside each leg. Try on jeans and see if the length suits you.

6 Iron your jeans. Iron the new crease to soften the folded fabric and give your jeans the ultimate perfect length without excessive hemming marks.
