I was having an issue and reinstalled krita to the latest version, 5.2.6 on windows. Now everything is tiny!!! I resized everything (even hidpi, did nothing) but the the whole row up top with the save, open, new, brush settings, ect buttons are still so tiny and i dont know what to do!!! Please help is gonna start crying, why did they have to change the size.
UPDATE :
Its the tool bar that is tiny, everything else is fine now.

Hi. Read through this thread, there are various suggestions there (please especially first check the points about the Settings):
Scaling Needs Attention - Develop / Artists Feedback & Testing - Krita Artists
Ive done the ui scaling but it only resized the words
If you are already using HiDpi and fractional scaling:
Then I think the only thing you can do to enlarge the icon is to increase the screen scaling in Windows to 150% or 200% maybe:
The only thing that comes to my mind, is maybe before you were using Minimal workspace layout – this adds Tablet-friendly big undo keys and such:
How do i get to scale and layout?
You can right click on a free space in the tool bar and then there should open a small context menu where you can change the icon sizes. This only affects the tool bar not the other icons of the software.
that only worked for the one below, I’m looking to resize the one labeled as toolbar under settings and I cant right click it
Scale and layout is Windows system screen scaling. You can right click on the desktop and choose display settings.
Krita’s Scripter can help in scaling buttons at main tool bar.
(with some work script can be converted to Extension that is execute automatically for each new window that is opened in Krita)
from krita import Krita
from PyQt5.QtCore import Qt, QSize
from PyQt5.QtWidgets import QToolBar, QAbstractButton
size = QSize(256, 256) # change width and height to match your needs
qwin = Krita.instance().activeWindow().qwindow()
mainToolBar = qwin.findChild(QToolBar, 'mainToolBar')
mainToolBar.setIconSize(size)
mainToolBar.setToolButtonStyle(Qt.ToolButtonIconOnly)
layout = mainToolBar.layout()
layout.setContentsMargins(0, 0, 0, 0)
layout.setSpacing(0)
layout.layout().setAlignment(Qt.AlignLeft | Qt.AlignVCenter)
for i in range(layout.count()):
l_item = layout.itemAt(i)
l_item.setAlignment(Qt.AlignCenter)
for widget in mainToolBar.findChildren(QAbstractButton, '', Qt.FindDirectChildrenOnly):
widget.setContentsMargins(0, 0, 0, 0)
widget.setMinimumSize(size)

definitely made the main toolbar icons bigger, edit & brushs still small but this helped out a lot, thank you 
And here is a better adjusted version of the script.
from krita import Krita
from PyQt5.QtCore import Qt, QSize
from PyQt5.QtWidgets import QAbstractButton, QWidget, QToolBar, QLayout
size = QSize(50, 50) # change width and height to match your needs
qwin = Krita.instance().activeWindow().qwindow()
for tool_bar in qwin.findChildren(QToolBar, None, Qt.FindDirectChildrenOnly):
tool_bar.setIconSize(size)
tool_bar.setToolButtonStyle(Qt.ToolButtonIconOnly)
layout = tool_bar.layout()
layout.setContentsMargins(0, 0, 0, 0)
layout.setSpacing(0)
layout.layout().setAlignment(Qt.AlignLeft | Qt.AlignVCenter)
for i in range(layout.count()):
l_item = layout.itemAt(i)
l_item.setAlignment(Qt.AlignCenter)
for widget in tool_bar.findChildren(QWidget):
widget.setContentsMargins(0, 0, 0, 0)
widget.setMinimumSize(size)
for widget in tool_bar.findChildren(QAbstractButton):
widget.setIconSize(size)
for sub_layout in tool_bar.findChildren(QLayout):
sub_layout.setContentsMargins(0, 0, 0, 0)
sub_layout.setSpacing(0)
for i in range(sub_layout.count()):
l_item = sub_layout.itemAt(i)
l_item.setAlignment(Qt.AlignCenter)
