[h], [t], [b], [p], and [H] do not mean “put the image exactly here” in the way many beginners expect. This guide explains what each option actually does, why figures move, and how to get cleaner layouts without fighting the compiler.
Key concept: Figures are “floats” in LaTeX - they can move to optimize page layout. Understanding this behavior is essential for controlling positioning.
Understanding Floats
What Are Floats?
Floats are elements (figures, tables) that LaTeX can move to avoid awkward page breaks and maintain good typography. LaTeX uses sophisticated algorithms to determine optimal placement.Why Floats Move
LaTeX moves floats to:- Avoid large white spaces
- Prevent awkward page breaks
- Keep related content together
- Maintain consistent page density

How to Force a Figure to Stay in Its Own Section
A float can drift several pages past the point where it was declared, which often means it appears under the wrong heading. This is normal float behaviour, not a bug: LaTeX moves floats to wherever they fit. The reliable fix is a float barrier.\usepackage{placeins} provides
\FloatBarrier, which forces every pending float to be placed before the document
continues. Put it at the end of a section, and no figure can escape into the next
one.
\usepackage[section]{placeins} does this automatically at every \section, which
is usually what people want when they ask this question.
\clearpage also flushes floats, but it starts a new page, so it is a heavier tool.
Reach for \FloatBarrier first.
Forcing exact placement with [H] from float is a different thing and a worse
default — it disables floating entirely and tends to leave large gaps.
