This library doesn't do anything on item's height but the offset could change only the item's width. Maybe the middle item has a different width from the others and the height you are using is based on the width?

Edit: fix wrong number on picture

This is my solution

object : DividerOffsetProvider {
    override fun getOffsetFromSize(grid: Grid, divider: Divider, dividerSide: Side, size: Int): Int {
        if (divider.isTopDivider || divider.isBottomDivider || divider.isStartDivider || divider.isEndDivider) return size
        val gridOrientation = grid.orientation
        if (gridOrientation.isVertical && dividerSide == Side.TOP || gridOrientation.isHorizontal && dividerSide == Side.START) return 0
        if (gridOrientation.isVertical && dividerSide == Side.BOTTOM || gridOrientation.isHorizontal && dividerSide == Side.END) return size

        val sideDividerSize = 16.dp

        val cellsCount = grid.lines[divider.originY].cellsCount
        if (cellsCount >= 3) {
            val fixedSize = (cellsCount - 2) * sideDividerSize
            val allocatableSize = size * (cellsCount - 1) - fixedSize
            val averageSize = allocatableSize / cellsCount.toFloat()

            if (divider.originX == 1 && dividerSide == Side.END
                || divider.originX == cellsCount - 1 && dividerSide == Side.START) {
                return averageSize.toInt()
            } else {
                val middleCellDividerSize = (sideDividerSize + averageSize) / 2
                return middleCellDividerSize.toInt()
            }
        } else {
            return size
        }
    }
}
