Show Bounding Box for Any Object

Question

This seems like such a simple problem but I cannot seem to find an answer mixed in all the questions about drawing boxes.

I want to be able to draw a bounding, not a frame, but a bounding box. One with zero extra size around any object: a minipage, a paragraph, a tikz picture, a figure, a table, whatever.

For the purposes of illustrating how large something is on the page I want to encapsulate it a box. This means that adding the bounding box to the page must not change any of the page layout.

I of course expect these boxes to be ugly, their only purpose is for drafting needs to measure distances, similar to the showframe option for \geometry.

If my understanding about TeX is correct, everything ever drawn on a page is a box. Is there a way to simply draw this box?

EDIT-----------------------------------------------------------------

I have added a minimum working example depicting the problems with the (at the time of 1:53pm) suggestions so far.

\documentclass[fontsize=12pt,twoside=false,]{scrbook}
\usepackage{babel}
\usepackage{listings}
\usepackage{geometry}
\usepackage{parskip}

\usepackage{lipsum} % Just for the MWE


\begin{document}
%Phelype Oleiniks Suggestion
\fboxsep=0pt \fboxrule=1sp

%This doesnt work
\fbox{\lipsum[1]}

%This doesnt work either
\fbox{Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Ut purus elit, vestibulum

%Putting it inside a minipage works for unknown reasons.
\fbox{\begin{minipage}[t]{\linewidth}%
    \lipsum[1]%

%this even breaks the compiler

Answer 1

\frame{...} draws a frame around its content without additional space:

\documentclass{article}

\begin{document}
\sbox{0}{Hello!}\the\wd0, \the\ht0

\sbox{0}{\frame{Hello!}}\the\wd0, \the\ht0
\end{document}
