In Europe we've used regulations. There's standardised ways to measure area of an apartment/house, and it has to be included in any ads and contract of sale/rent. If the actual area doesn't match what's in the ads/contract the landlord/seller will be in trouble. I saw a news article once where the landlord,iirc, had to return all rent money to the tenant. The tenant had lived there for a while(memory is fuzzy, I think it was years, but don't quote me on that) and in the end only paid for electricity.

I hear you guys like suing eachother in the states, seems like this kind of regulation would suit you just fine!

The parent was talking about it being a "landlords market" and wanting that to be changed. I asked how that might be possible.

Improving advertisements to make them accurate, detailed, and directly-comparable is obviously a good thing. But does not change the market in favour of the tenants; the status-quo exists because of a lack of properties. That means no matter how bad the advert(s) tenants have to choose one available. If there were a surplus of properties then it would be a tenant's market.
