See what the height you are allowed actually looks like

A bylaw figure is an abstraction. “1.2 m in the street-facing part of the lot” means nothing to someone standing in their own front garden, and the gap between what people picture and what 1.2 m is at a boundary is the most common surprise in this trade: it is shoulder height, not head height, and most of the privacy they were imagining is not there. Mark two points of a known height in a photo of your own fence line and this draws the permitted height, and the alternatives, at the same scale.

What you enter

A photo of the line the fence will run along, with something of a known height in the shot
Two clicks: the ground at the base of that object, then its top
What the object is — a standard door, a person, the fence that is there now, or a height you type
Your municipality and whether the fence is street-facing or on a side or rear boundary

How it is calculated

The two clicks give a pixels-per-metre scale for that part of the photo; the lines are drawn from the ground point at that scale
The permitted height comes from your municipality's own bylaw through the same rules engine the rest of this site uses
Nothing is generated. No fence is drawn, no material is chosen and no picture is invented — the only thing added to your photo is a line and a number

What it is not

It assumes the fence will stand about as far from the camera as your reference object did. Put the reference near the fence line and it gets truer
It is a scale check, not a survey, and not the measurement the bylaw cares about — that one is taken on site from the grade your municipality measures from
Height is rarely the only rule. Retaining walls, corner sight triangles, trees, water setbacks and zone exceptions can all beat the figure, and the full rules check covers those

Start with a photo of the line the fence will run along, taken straight on. Something of a known height has to be in the shot — a door, a car, a person, the fence that is there now.

Your next step

Height is the figure people look up; retaining walls, corner lots and trees are what actually stop fences here.
