The Temple Rule Nobody Writes Down, and the Fine That Enforces It
The sign at the gate says shoulders and knees covered. It does not say that the enforcement is done by an uncle with a roll of tape who will absolutely wrap your knee without asking you first.
Almost every temple gate in Thailand has the same sign. Shoulders covered. Knees covered. No shoes. It is translated into a dozen languages and it is enforced not by staff but by whoever is nearest, usually a volunteer, usually an auntie, usually holding a roll of cloth.

Why the rule exists, which is not about you
Temples are working buildings, not museums. A wat is a residence for the monks, a school, a community centre, and a place of worship, all at once. The dress code is a sign of respect for the building and the people in it, and it is enforced most strictly in the inner courtyards, which are where the monks and the sacred stuff are.
This is why the rule is looser at some temples than others. A big tourist temple in Bangkok may have a member of staff at the gate and a rack of sarongs and not much else. A small rural wat with a monk in residence and no visitor infrastructure will be stricter, not looser, because there is no one employed to enforce it politely.
What you actually need
A top that covers your shoulders. Not your shoulders in the sense of a formal dress code, but in the sense that a vest with no sleeves does not cover them. A plain t-shirt is fine. A shirt is fine. A singlet is not, and this is the single most common reason people get turned around.
Something below the knee. Long trousers, or a skirt or dress below the knee. A man in shorts to the knee is generally fine. A man in shorts above the knee will be asked.
Your shoes off, and socks if you want. Shoes off at the outer gate, sometimes a second time at the inner sanctum. Socks off is not required but is a nice touch and nobody will ask you to do it.
That is the whole list. It is not a strict dress code, it is three items, and it applies to everyone including Thai people, who also cover up.
The sarong situation
Every temple of any size has a box or a rack of cloth near the entrance. It is not a rental business, it is a donation box that doubles as a lending service. You wrap it, you return it when you leave, and there is a donation box for the ones you would like to leave behind.
The cloth is usually a long sarong or a piece of printed cotton. The way to wrap it is around the waist, not around the knees, and if you are a woman you can also drape it over the shoulders. Getting this right takes about four seconds and looks respectful. Wrapping it badly is more conspicuous than showing your knees.
Do not photograph the auntie. Do not photograph the auntie's daughter. Do not ask whether you can take a photograph while she is standing there holding the thing you need to wear.
How strict is strict, in practice
Wat Phra Kaew and the Grand Palace in Bangkok: strictest. Full-length trousers required, no vest, no ripped jeans, no shorts at all, no photograph of any Buddha image inside. The enforcement is by officials and it is not negotiable. This is the one place in the country where you will be genuinely turned away.
Wat Arun, Wat Pho, the major Bangkok temples: moderate. Staff, sarongs available, generally a friendly correction rather than a refusal. Bare shoulders get you a wrap.
Chiang Mai's Doi Suthep and the old city temples: moderate to casual. Sarongs at the gate, and the enforcement varies by how busy the day is. At Songkran it is basically abandoned, which I have covered separately.
Rural wats: strict and unfussy. No sarongs on the rack, someone will go and get one, and the expectation is that you cover up because there is a monk living there and you are in his home.
The three things that are actually rude
Pointing your feet at a Buddha. Feet are the lowest part of the body and a Buddha image is the highest significance. Do not sit with your feet toward the altar, and do not recline with your feet into a shrine room. Everyone gets this wrong and almost nobody knows why it is wrong.
Turning your back to a Buddha image. This is why you will be asked to kneel and bow when you enter a room with a large image. Bowing three times, and then sitting sideways, is the correct behaviour. You do not need to believe anything; you need to not turn your back.
Touching a monk, or handing something to a monk directly. Women should not touch monks or hand them objects, and should not hand them anything at all if avoidable. This is a real Thai custom with real consequences socially, and the woman who does it is the one who gets looked at.
The version nobody enforces but you should follow
Do not stand with your hands on your hips inside a temple. Do not talk loudly. Do not walk through a group of monks without stepping to the side. And do not walk backwards out of a shrine room, which almost everyone does and which is the one gesture that reads as genuinely disrespectful in a way that shorts are not.
None of that is enforced. All of it is noticed, and locals read it instantly, and it is the difference between being treated as a guest and being treated as a tourist who cannot be bothered.
