The Writer's Weigh Scale



This is a tool for calculating how much an envelope with pages and an SASE weighs. It's for those evenings when you MUST mail something, but the post office is already closed. (In other words, when it's the last day of the month and you're trying to avoid a butt-shredding from McKoala in her Year of Submission challenge.)

To affix proper postage to your envelope, all you need to know is its mass, correct? The Writer's Weigh Scale calculates that for you, because goodness knows a bathroom scale is useless for a fifteen-page story.

Now, here's my dread' secret: I don't have very accurate mass values for the envelopes yet, particularly the non-North American sizes. For that matter, I don't even know if the DL, C5 and C4 envelope sizes are really the most commonly-used ones for people who type on A4-sized paper.

Hence, I have a favour to ask of my UK friends (bats eyelashes at FairyHedgehog and Whirlochre). Could you:

1. Let me know which envelope sizes you normally use for story submissions and SASEs? Measurements are fine if you don't know the actual name for that type of envelope.
   
   
2. If you have access to an accurate scale, could you weigh one (or even better, a stack) of any of these envelopes and tell me the mass(es)? Thank you in advance to anyone who can help me out with this!

As for my 'Merican de la North friends, you're also welcome to weigh envelopes for me and report the results, although I will get around to that myself eventually, assuming I remember to schlep some envelopes in to work with me one of these days.

I hope you'll find The Writer's Weigh Scale useful. Please feel free to disperse the URL to anyone you think might also find it handy.

And finally, do you have any suggestions for how to make The Writer's Weigh Scale better? When you tried it out, did you discover any glitches? Please let me know of anything you think should be improved, and thank you very much for your help!
