Every number on this page is arithmetic you can check: Torchline budgets 1,800 XP per character at level 12 for a standard fight, scales it by party size, then by the difficulty band. Below each table are the SRD 5.1 creatures that actually land in that budget.
Budgets by party size and difficulty

Party of 4
Party of 5

Skirmish — resources barely dented
2,970
3,960
4,950
5,940
Standard — a real fight, rarely lethal
5,400
7,200
9,000
10,800
Hard — someone will probably go down
8,640
11,520
14,400
17,280
Brutal — a character can die here
12,960
17,280
21,600
25,920
These are effective-XP budgets: a group of monsters is multiplied up before it is compared against them, so a budget of 7,200 does not mean 7,200 XP of monsters.
What actually fits, for a party of four
The crowd multiplier is the part that catches people out. Two creatures count for 1.5× their XP, three to six count double, seven to ten count 2.5×, eleven or more count triple. So the XP you can spend per creature falls fast as the group grows.
Skirmish — budget 3,960
A lone threat — about 3,960 XP each (×1 crowd multiplier)
