另外,比较流行的电影,一般是 1920*1080 像素,也就是 16:9,16:10 的比例也比较常见,比值约为 1.7 左右。那么,宽 1 厘米的平板,长 1.7 厘米比较符合商业惯性。长度四舍五入了,1.7 厘米记作 2 厘米。对角线尺寸四舍五入,保留了一位小数。对角线尺寸,即为商家标示的平板尺寸。7.8 英寸的平板,足以应付绝大多数学习需求。当然,因为存在四舍五入,这一切都只是近似值,仅供参考。 | |||

买平板电脑时,价格、场景、屏幕、系统、品牌,都是应该考虑的因素,但还有一个因素,易被忽略,那就是尺寸。尺寸太大或太小,不符合使用场景,平板就会吃灰。
在标记长宽时,商家用厘米。在标记平板尺寸时,商家用英寸,且平板尺寸一般指屏幕对角线的尺寸。商品尺寸会比屏幕尺寸多个边框的距离。厘米、英寸两个单位的不一致,导致用户很难判断自己需要几寸的平板。
以下提供一张自制的长宽英寸对应简表,供大家选购平板电脑时参考。加粗且无小数部分的,单位为厘米。表格正文常规粗细的,单位为英寸,四舍五入,取一位小数。表格解读,一台长 15 厘米,宽 7 厘米的平板,机身即为 6.5 英寸,这个数值比商家标的大一些,因为这是机身,商家卖时特指屏幕,减去边框才是卖值。

另外,比较流行的电影,一般是 1920*1080 像素,也就是 16:9,16:10 的比例也比较常见,比值约为 1.7 左右。那么,宽 1 厘米的平板,长 1.7 厘米比较符合商业惯性。长度四舍五入了,1.7 厘米记作 2 厘米。对角线尺寸四舍五入,保留了一位小数。对角线尺寸,即为商家标示的平板尺寸。7.8 英寸的平板,足以应付绝大多数学习需求。当然,因为存在四舍五入,这一切都只是近似值,仅供参考。
