How do I make my handlebars straight?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Don't forget to account for the curvature of the earth.

I don't think the earth's curve matters since I'm using 25mm tires and aluminum rims.

Careful, bro! You almost put false information on the internet!

Just get a long piece of string and tape it to the center of your tire, run the string up across your stem and down to your TT.

If your stem clamp isn't offset on the steerer tube, turn the front wheel, and line up the gap in the clamp on the rear of your tire along with centering the front of the tire between the stem bolts on your handlebars - kinda like a rifle sight - works for me.

Straddle top tube, sight down the bars to the fork tips. Move back and both fork tips should get covered at the same time.

Yup! Another way I do it too! This, and ride with a 4mm allen, adjust on the road.

i used to obsess about this stem/bar alignment especially when riding, i sometimes notice that the bar seems a bit askew relative to the front wheel. later realised it also depends on how you are seated on the saddle at the time. from then on, just did not bother with it. i figured 1 or 2 mms either side would not make much difference. i sight the bike from the rear and align using an imaginary straight line from the rear of the saddle to the nose then centre of the stem

I run a string from the stem to the hub and measure the distance from the rim to the string on both sides.

I look from the front and then I look from the saddle.
Repeat 20 times until my OCD starts to piss me off. At that point I tighten everything and flip off my bike.

I use a cross line laser. After bike is leveled in stand: Center on down top tube and seat post. laser line will be centered on stem cap nut. align stem, head tube and tire..... OCD but it will the straightest that I will be able to get it with repeatable results.

I have always just thrown a broom on the ground. I take my wheel off, place the fork dropouts on the broom, and line up the tips of the handlebar so that they are parallel with the broom handle.

If I was one of your riding buddies i would wait for a break, look at your bike, squint and say "are your bars straight?" like every single week just to drive you crazy.
