    How do I increase evenly across a row?

    Subtract any stitches the increase uses up, divide the rest by the number of increases, and work that many stitches between each one. The calculator does the division and spreads the leftover stitches for you.

    How do I space 7 increases across 92 stitches?

    In the round: K14, M1 once, then [K13, M1] 6 times, for 99 stitches. Worked flat, the first and last plain stitches are split so no increase sits at the edge.

    Is it different for crochet?

    Yes. A crochet increase (2 sc in one stitch) uses up a stitch, so there are fewer plain stitches between increases. Choose Crochet and the count is adjusted.

    How the calculator spaces your stitches

    Every increase or decrease sits between groups of plain stitches. The calculator removes the stitches the shaping itself uses (none for M1, one for a crochet increase, two for k2tog or sc2tog), divides the rest by the number of increases or decreases and spreads any leftover stitches so no group differs from another by more than one.

    Worked flat, one group is split between the beginning and end of the row, so the first and last stitches stay plain. In the round, every group is the same length or one longer, because there is no edge.
