I was confused by this until just now, so here's how I've understood this.
Size indicates the size of a specific order.
Sum gives you the total size of a currency available for that price.
That is, in the image below:
As you move down the chart, the "Sum" corresponding to an order is the sum of all the sizes up to an including that order.
My pseudo economic analysis: Sum is an necessary indicator of the true price. If the cheapest Ask order has Size 0.5 USD, that ask price doesn't tell you much.
