Resize your SVG by defining width and height in the <svg> tag or more effortlessly, through CSS. Apply the viewBox attribute to scale while maintaining aspect ratio.

Example:

<svg width="200" height="100" viewBox="0 0 400 200">
  <!-- your awesome SVG shapes go here -->
</svg>

CSS:

svg { width: 200px; height: 100px; 
    /* taking control of my SVGs like a boss */}

Think of the viewBox as your remote control for scaling; width/height to set the size.

If you're into responsiveness and dynamism (who isn't?), you'd rather ditch the fixed pixel values for slick percentage values. Let the SVG dimensions bow to the will of the container!

.container {
  width: 50%; // Look at me, I'm the captain now!
}

.container svg {
  width: 100%;
  height: auto; // Hello responsive design!
}

Navigating aspect ratios and responsive scaling

To ensure the SVG scales effortlessly despite the container size, use a combination of viewBox and preserveAspectRatio. They are the Batman and Robin of SVG scaling, maintaining SVG's proportions no matter what.

viewBox defines an internal coordinate system of the SVG, allowing fluid scaling. On the other hand, the preserveAspectRatio attribute controls how the SVG performs in cases of disproportionate scaling. preserveAspectRatio="xMidYMid meet" ensures the SVG scales uniformly like good ol' milk.

<svg viewBox="0 0 400 200" preserveAspectRatio="xMidYMid meet">
  <!-- SVG content -->
</svg>

The viewBox can extend to the total dimensions of the SVG with viewBox="0 0 width height". This flexibility allows the SVG to scale up or down while preserving its original proportions. Meaning, it can grow or shrink without marauding your design!

Precision and control over SVG transformations

In some scenarios, you demand more control over scaling, especially when SVGs house multiple elements, because who doesn't love stunning complex SVGs, right? Use the <g> element strategically with the transform attribute:

<svg viewBox="0 0 400 200" xmlns="http://www.w3.org/2000/svg">
  <g transform="scale(0.5)">
  <!-- Adjusting my own SVG gym for a 50% workout reduction -->
  </g>
</svg>

It also prevents annoying pixelation, as SVGs are resolution-independent. Do remember to include XML namespaces when they might be AWOL, for fantastic cross-browser compatibility:

<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 400 200">
  <!— SVG content -->
</svg>

Play with various symmetrical or radical scale values for fine-tuning the SVG size to have that perfect fit for your design - fashion designers, you know what I'm talking about!

Ensuring optimal SVG display

Test your SVG scalability for optimal display across different devices. Assume nothing except that SVGs will behave like a bull in a china shop unless checked!

Also, multitasking concerns: when you edit the SVG's XML to set manual dimensions, respect the visual integrity of the graphic. Adjustments should feel like a nice spa, not invasive surgery.

Let's skip the HTML <object> or <embed> tags for resizing to avoid extra space they might bring ("extra luggage fee, anyone?"). Use the <img> tag with responsive width for a Tim Gunn level "make it work" moment:

<img src="image.svg" style="width: 100%;" 
    /* My width is adjustable like a comedian's pants! */ />
