I'm building a small wall unit with narrow shelves that will be attached to the back panel as well as the sides. I doubt that the "Sagulator"
TIA

Intuitive, non-engineer answer: Too many other variables to be able to answer the question. Some pertinent factors: stiffness of the back, stiffness of the sides, other shelves (which will tend to stiffen the sides, making them less able to twist to accommodate a sag of one edge of the shelf in question). Probably lots of etc's I'm not thinking of.
In general, if a shelf is suported on 3 sides (and I'm working with stock of any real thickness - say 3/4" or more), I tend not to worry about shelf sag unless the shelf is really wide.
I have some pine bookcases I built about 30 years ago - they're a full foot deep, supported on 3 sides (grooves in the plywood back and wood sides),
3/4" stock. they've held my dad's engineering library since they were made (big, heavy books), and there is a *slight* sag in the middle. Barely noticable unless you actually sight along the edge.YMMV

I agree; I'm not gonna worry about the sag since the shelves will be supported in dados and secured to the back as well.

Wow! Bay Area Dave! Haven't seen that moniker for a decade or so.
And as for CruzR, whatever that may be, you have no clue. Not about Usenet, nor about "you folks".
Here is my Sagulator, it is the LFAT model.
