You don't need to be a professional fitter to catch an obviously poor fit — a handful of simple checks, done consistently, will catch a lot of problems well before they become serious. None of these checks replace a professional opinion when something seems genuinely wrong or borderline. What they do is give you a routine you can run yourself, regularly, so you're not relying on guesswork or waiting for a problem to become visible in your horse's behavior.
With the saddle on but not girthed, or girthed loosely, check the gap between the underside of the pommel and the top of the withers — you want clear daylight, not contact, and enough room that the gap doesn't close up when a rider's weight goes into the seat. A saddle that touches down on the withers, especially on a higher-withered horse, is pressing on sensitive tissue with bone close to the surface.
Check this both standing square and with the horse's head lowered, since a raised or lowered neck changes the shape of the back underneath and can open or close that gap more than people expect.
Stand back and look at the seat from the side — it should sit roughly level, not tipped down at the front or back. A seat that's tipped forward often means too much wither clearance or a gullet that's too wide; tipped back can mean the opposite, or a tree shape that doesn't suit this horse's back. Neither is just a rider-comfort issue — a tipped seat usually means weight is being pushed toward one end of the panel instead of spread evenly.
Next, run a hand flat underneath the panel along its whole length, not just at the front. You're feeling for even, consistent contact — no gap in the middle (bridging), no rocking when you press down at one end, no single spot that feels noticeably firmer than the rest.
Have someone walk the horse forward a few steps while you watch the point of the shoulder move underneath the front of the saddle. The shoulder should move freely without the saddle's edge catching or restricting it — a saddle set too far forward, or with a tree too narrow through the front, can visibly interfere with that motion.
Check the girth line too: it should hang roughly perpendicular to the ground, not pulled forward toward the elbow or backward toward the belly. A girth line that's noticeably off usually means the saddle isn't sitting where it should, which can be a placement problem rather than a fit problem — worth ruling out before assuming the saddle itself is wrong.
You'll hear riders talk about a "three fingers" rule for both wither clearance and English saddle placement — as a rough guide, roughly three fingers' width of clearance at the pommel, and an English saddle sitting about three fingers behind the shoulder blade. It's a genuinely useful rule of thumb precisely because it doesn't require any equipment, just your own hand. Treat it as a quick sanity check, though, not a precise measurement — hands vary in size, and it's meant to catch an obvious problem, not replace an actual measurement or a fitter's assessment on a borderline horse.

Every check above is worth doing twice: once with the saddle directly on the horse's back, and again with the pad you actually ride in underneath it. A pad changes the effective fit — sometimes enough to turn a comfortable bare fit into a tight one — so a check done only bare can miss a problem you'll actually ride with. This is covered in more depth elsewhere on this site, but it's worth repeating here since it's easy to forget as a step.
Finally, remember these are screening checks, not a diagnosis. Persistent problems, or anything borderline, are worth a professional fitter's opinion rather than a guess — self-checks are for routine maintenance, not for settling a real doubt.
