A fixed shelf makes you reach into the cabinet. A pull-out brings the cabinet to you. It is the same volume either way, but only one of them is storage you use rather than storage you own.
Kneeling down and reaching past three things to find a fourth is the reason base cabinets end up holding one layer of useful items and a graveyard behind them. A roll-out shelf on runners removes the reaching entirely: the shelf travels out, you look down at all of it, and it goes back.
The gain is bigger in tall and deep cabinets than people expect, and biggest of all in the ones under a worktop where you are also bending. Pans, small appliances and bulk dry goods are the usual occupants, because those are the things nobody wants to excavate for.
It is the same principle a pantry unit uses at full height and a corner mechanism uses on a diagonal, and in most kitchens all three end up doing their share of the work. See the storage hub for how they fit together.

How it works
How a Pull-Out Is Fitted
Pick the cabinets that annoy you
Not all of them. The two or three you kneel at daily are where this pays; the cupboard you open at Christmas is not worth a mechanism.
Measure inside, not the door
Internal width between the carcass sides, minus what the face frame and hinge plates steal. A pull-out ordered off the door width does not fit, and that is the commonest error.
Rate the runner to the contents
Heavy-duty for tins and pans, standard for dry goods and plastics. Full extension where the whole depth matters, which on a base cabinet is nearly always.
Fit and check the swing
Fitted while the doors are off, then tested with the door closed to make sure nothing catches on the hinge or the handle as it comes out.
The runner question
Weight Decides the Runner, Not Width
This is the part that gets specified badly. A pull-out full of tinned goods or a stack of cast iron is heavy, and runners are rated for load, not just for length. Fit a light runner under a heavy shelf and within a year it drops at the front, binds on the way out and eventually stops closing square.
So we ask what is going in before ordering anything. Pans and tins get a heavy-duty runner. Dry goods and plastics do not need one, and paying for it there is money that would do more good on another cabinet.
Full extension matters as much as rating. A three quarter extension runner leaves the back few inches still inside the cabinet, which is exactly the part you were trying to reach. Soft-close runners are the usual pairing, accessories cover the rest, and dividers keep the contents still.

The Rest of What Goes Inside
Pull-outs are one fix. These are the others, and most fit cabinets you own.
Where they pay, what they cost, and what makes one fail.
Usually, provided the internal width and the door opening allow it. The saving is in timing rather than possibility: fitted during a reface it is an hour, fitted later it is a separate visit.
The deep base cabinets you kneel at daily. Pans, bulk dry goods and small appliances. A cupboard you open twice a year does not justify a mechanism, and we will say so.
An under-rated runner. Weight, not width, decides the rating, and a light runner under a shelf of tins drops at the front within a year. It is the question people forget to ask.
On a base cabinet, nearly always. A three quarter extension leaves the last few inches inside the cabinet, which is precisely the part you installed the pull-out to reach.
Slightly in raw volume, because the runners and the shelf sides take a little width. In usable storage it increases it substantially, because all of the depth becomes reachable.
Yes, and it suits tall base cabinets well: a deeper one below for pans and a shallower one above for jars. The spacing is set to what you actually store.
On something heavy, yes. A loaded pull-out closing hard puts real force through the front of the cabinet, and the damper takes that out. It also stops the contents rearranging themselves.
